Five-Star Conversion Study — Michigan vs the Field
How often does a 247Sports Composite five-star recruit actually become a star for the program that signed him? Every five-star from the 2006–2025 classes, graded on college production and honors only — NFL success never inflates a tier.
Final answer on the question you asked: Michigan finishes 3rd of 20 in elite rate and 2nd of 20 in star+ rate, on the 14th-largest five-star haul in the study. Only Alabama (46.6%) and Ohio State (38.6%) convert five-stars into elite players at a higher rate; only Clemson (59.4%) edges Michigan on star-or-better. Michigan's deficit against the sport's recruiting superpowers is a supply problem, not a development problem — 14 five-stars in twenty years against Alabama's 79.
The honest caveat: Michigan's numbers rest on 12 graded players. The 95% Wilson interval on its 58.3% star+ rate runs roughly 32–81%, which overlaps Clemson, Alabama and Ohio State. Michigan cannot be separated statistically from the leaders. What the data does establish cleanly is the negative — Michigan is nowhere near the programs that genuinely waste blue-chip talent, and no cut of these 525 players supports the claim that it does.
Three high-volume programs, three completely different shapes. Alabama is barbell-shaped: 46.6% elite, 38.4% miss, only 6 solid starters in 73 graded. Georgia is middle-heavy: 7.4% elite but 30 of 54 became multi-year starters. Ohio State sits between them at 38.6% elite with a manageable 27.3% miss. USC is the cautionary case — 48 five-stars, the same volume as Ohio State, and a 12.5% elite rate with 37.5% missing. Georgia's low elite rate is a roster-stacking artifact: six of its national-title-team starters never earned first-team All-SEC.
Clemson avoided the downside better than anyone: zero T4 players and two T5 in 32 graded. A 6.3% miss rate against a 30.7% field average. Where Alabama's model was volume plus a high ceiling and a high floor-failure rate, Clemson signed a third as many five-stars and almost never wasted one — 93.8% became at least a multi-year starter.
Program comparison — sorted by star+ rate
Rates use graded players only; active players with no qualifying honor yet are excluded from every denominator. Confidence intervals are Wilson score intervals at 95% — note how much wider the low-volume programs are.

Volume vs conversion
Each point is a program. If anything, conversion rate falls as volume rises — consistent with five-stars at stacked programs being blocked by other five-stars.

Assessment
The rubric
Grades measure what the signing program got. A player who was mediocre in college and became an NFL All-Pro is still T3 or T4.
Tier
Criteria
T1 Elite
Any one of: postseason first-team All-America from a major selector (AP, AFCA, FWAA, Walter Camp, TSN, ESPN, SI, USA Today, CBS); a national award won; a conference MVP or position-Player-of-the-Year award; a national championship game offensive or defensive MVP; or primary starter on a national title team who also earned first-team all-conference
T2 Star
At least one first-team all-conference selection (coaches or media), no T1 trigger. Number of starting seasons is irrelevant
T3 Starter
≥10 career starts and at least one season starting a majority of games played
T4 Marginal
Fails T3 but had real production: ≥4 starts, ≥20 games with production, ≥500 passing yards, ≥250 rushing or receiving yards, or ≥25 tackles
T5 Non-Factor
None of the above — essentially no production, or never played
Active
Still on the signing school's roster with eligibility remaining and no T1/T2 trigger yet. Excluded from all rates. A player who transferred out is graded on what the signing school got; an active player who already has a T1/T2 trigger is graded, not deferred
What the comparison shows so far
Michigan is top-three on both headline rates, and nothing separates the leaders statistically. Alabama and Ohio State clear it on elite rate; Clemson edges it on star+. All four sit inside overlapping confidence intervals. What can be said cleanly is that the popular notion that Michigan wastes blue-chip talent is not supported by any cut of these 525 players.
Alabama alone produced more elite players than any other program by a factor of two. 34 T1 outcomes; Ohio State is next at 17. It is not a small-sample artifact — it rests on 73 graded players.
Clemson is the efficiency champion and the study's cleanest counterexample to volume. Zero T4 players and two T5 in 32 graded, a 6.3% miss rate against a 29.1% field average, and 93.8% becoming at least a multi-year starter. Clemson signed a third of Alabama's five-stars and almost never wasted one.
Winning titles and producing decorated individuals are different things. Georgia won back-to-back national championships with a 7.4% elite rate. Six of its title-team starters never made first-team All-SEC. LSU is the same story in miniature: four primary starters on its 15-0 2019 champion — Fulton, Lawrence, Stevens, Marshall — all grade T3 because none ever made first-team All-SEC.
USC is the largest underperformance in the study. The same 48 five-stars as Ohio State, less than a third the elite rate (12.5% vs 38.6%). Twelve five-stars in 2006–2007 alone produced one T1. The 2010–2012 NCAA sanctions are a genuine confound, but the underperformance predates and outlasts them.
UCLA is the clearest failure: 0-for-10. Not one UCLA five-star in twenty years earned a first-team all-conference selection. Its two highest-rated signings ever — Jaelan Phillips (No. 1 overall) and Dante Moore (No. 5) — both left without producing.
Volume does not predict conversion. The high-volume tier leads on elite rate (27.9% vs 20.2% mid and 12.8% low), but that is almost entirely Alabama and Ohio State — Georgia and USC sit near the bottom of the whole study. A five-star at a stacked program competes with other five-stars for the same job, which argues against reading conversion rate as pure development quality.
Attrition is the dominant failure mode in the portal era. Texas A&M's 2022 class had eight five-stars, four of whom produced essentially nothing before transferring. Alabama lost six to the portal after Saban retired. Michigan's non-factors also left — but neither is a clean evaluation miss: Ryan Mallett fled a coaching change and became an SEC star, and Aubrey Solomon transferred after knee surgery.
The median five-star is a good starter, not a star and not a bust. 193 of 525 graded players (36.8%) are T3 — multi-year starters who never made first-team all-conference. Matt Barkley is the emblem: the No. 1 overall recruit in 2009, 47 starts and 12,327 yards at USC, never once first-team all-conference.
Method. The national 247Sports Composite ranking page was read for each class 2006–2025, capturing every five-star and his signing school — 659 signees nationally plus one honorary posthumous ranking. Each of the twenty programs was then independently re-scraped against a per-year checksum before grading, and all twenty matched exactly. Career outcomes come from school athletics bios, Wikipedia, NCAA statistics, conference award releases and per-year All-America team records.
Known data issues. 247Sports lists Trey Metoyer twice in the 2011 class, so Oklahoma has 20 unique signees and the in-scope population is 585, not 586. LeSean McCoy appears as a 2006 Miami signee but never enrolled and is graded T5 pending a decision on whether to exclude never-enrolled players. Notre Dame has no conference, so the T2 first-team-all-conference gate is unavailable; a major-selector second/third-team All-America substitute was applied to one player, making Notre Dame's T2 rate not strictly comparable. Career start totals are unpublished for many pre-2015 players and a number are reconstructed estimates — these are itemised per player in the source CSVs.
Fragile grades worth review. Seven T1s rest on a single qualifying All-America selector (Bullard, Adolphus Washington, Jernigan, Kirkpatrick) or on the national-title-starter trigger alone rather than on All-America or an award (Julio Jones, Calvin Ridley, O.J. Howard, Tee Higgins, Broderick Jones, Mario Edwards Jr., TreVeyon Henderson). Removing the title-starter trigger would cut Alabama's elite rate to roughly 43% and drop Clemson and Georgia by one T1 each. Conversely, Stafford, A.J. Green and Beanie Wells fall below T1 only because their first-team All-America nods came from Pro Football Weekly or Rivals, outside the approved selector list.
