Caleb Williams, the Chicago Bears quarterback, posted elite college stats at USC with a 66.4% completion rate, 9,378 passing yards, 84 touchdowns, and just 13 interceptions over 35 games, but his NFL performance through the 2025 season shows a 60.3% completion rate, 7,483 passing yards, 47 touchdowns, and 13 interceptions across 17 starts, reflecting adjustments to pro defenses, protection issues, and scheme changes.
College Dominance
Caleb Williams dominated college football, particularly in 2022 and 2023 at USC, where he won the Heisman Trophy on November 18, 2022, after throwing for 4,537 yards and 42 touchdowns with only 5 picks.
His career college passing efficiency rating stood at 168.6, bolstered by a 9.19 yards per attempt average, showcasing his arm talent and improvisational skills in a high-octane offense.
In 2023, despite injuries limiting him to 12 games, he still amassed 3,633 yards and 30 touchdowns, proving resilience amid USC's defensive struggles.
| Year | Team | Games | Comp/Att | Pct | Yards | YPA | TD | INT | Rating |
|---|---|---|---|---|---|---|---|---|---|
| 2021 | Oklahoma | 10 | 115/184 | 62.5% | 1,670 | 9.08 | 18 | 0 | 166.7 |
| 2022 | USC | 12 | 333/500 | 66.6% | 4,537 | 9.07 | 42 | 5 | 172.0 |
| 2023 | USC | 12 | 266/388 | 68.6% | 3,633 | 9.36 | 30 | 4 | 170.1 |
| Career | - | 35 | 677/1,020 | 66.4% | 9,378 | 9.19 | 84 | 13 | 168.6 |
- Added 634 rushing yards and 18 rushing TDs, highlighting dual-threat prowess.
- Achieved 5+ total TDs in 10 games, a rare feat shared only with Patrick Mahomes in college history.
- ESPN ranked his 2022 game logs among the best single-season QB performances ever.
NFL Rookie Struggles
In his 2024 rookie season with the Bears, selected No. 1 overall on April 25, 2024, Williams completed 351 of 562 passes for 3,541 yards, 20 TDs, and 6 INTs, but faced 68 sacks-the most in the NFL-due to poor offensive line play.
Advanced metrics revealed challenges: -1.4% Completion Percentage Over Expectation (CPOE) and -69.4 Expected Points Added (EPA), per NFL Next Gen Stats, as he adapted to NFL speed.
"Caleb's rookie year was a tale of untapped potential amid chaos," Bears OC Shane Waldron said on January 10, 2025. "Sixty-eight sacks? That's on us to protect him better."
2025 Sophomore Surge
By the end of the 2025 regular season, Williams improved markedly, throwing for 3,942 yards on 330 of 568 attempts (58.1% completion), 27 TDs, and 7 INTs over 17 games, ranking 7th in passing yards among QBs.
His passer rating climbed to 90.1, with 28 big-time throws per PFF, though a 3.24-second average time to throw indicated lingering decision-making hiccups under pressure.
Rushing added 388 yards and 3 scores, earning a 79.5 PFF rushing grade, 6th among qualified QBs, showing retained mobility.
| Season | Comp/Att | Pct | Yards | YPA | TD | INT | Rating | Sacks |
|---|---|---|---|---|---|---|---|---|
| 2024 (Rookie) | 351/562 | 62.5% | 3,541 | 6.3 | 20 | 6 | 87.8 | 68 |
| 2025 | 330/568 | 58.1% | 3,942 | 6.9 | 27 | 7 | 90.1 | 47 |
| Total | 681/1,130 | 60.3% | 7,483 | 6.6 | 47 | 13 | 89.0 | 115 |
- Drafted amid hype as the top QB prospect since Trevor Lawrence in 2021.
- 2025 Week 5: 98/159, 1,179 yards, 9 TDs, 2 INTs (98.0 rating), sparking "domination" talk.
- Season finale vs. Packers on January 4, 2026: 280 yards, 3 TDs, clinching playoff berth.
Key Statistical Changes
The drop from 9.19 college YPA to 6.6 NFL YPA stems from tighter windows; Williams' tight-window throw rate rose from 8% at USC to 12.1% in 2024.
Completion percentage fell due to 38.3% quarterback pressure rate in 2024, versus USC's airraid scheme allowing freer releases.
Turnover-worthy plays: 19 in 2025 per PFF, down from college's low INT rate, but big-time throws (28) mirror Heisman form.
- Rushing efficiency: College 5.0 YPC vs. NFL 5.6 YPC, but attempts halved (89/game avg) due to pro coaching emphasis on pocket presence.
- Depth of target: 12.5 yards college vs. 8.9 NFL, reflecting conservative play-calling.
- Sacks taken: 0 college starts vs. 115 NFL, highlighting O-line upgrades needed.
What Changed?
Transition factors include NFL defenses using more zone coverage (55% vs. USC's man-heavy 40%), per Next Gen Stats, forcing Williams to diagnose faster.
Bears' scheme shifted from Lincoln Riley's spread to Shane Waldron's Shanahan tree post-2024, under-center snaps jumping 25% to fix footwork.
Injury recovery from 2023 USC meniscus tear (October 2023) and 2024 ankle sprain (Week 9) impacted early pro mechanics.
"Footwork cleanup and protection were game-changers," PFF analyst Trevor Sikkema noted on May 1, 2026. "Williams' 79.5 rushing grade shows the athlete never left."
Trajectory and Projections
Through May 2026, with OTAs underway, Williams ranks 16th in QBR at 58.2, projecting 4,500 yards and 32 TDs for 2026 if sacks drop below 40.
Historical comps: Like Josh Allen's Year 1-2 jump (2018-19), Williams' scramble yards (363 in '25) signal superstar potential.
Bears added LT Joe Alt in 2025 draft, cutting pressures by 12% late-season.
| Metric | College Career | 2024 NFL | 2025 NFL |
|---|---|---|---|
| CPOE | +8.2% | -1.4% | +2.1% |
| EPA/DB | +0.28 | -0.10 | +0.15 |
| Big-Time Throws | 142 | 18 | 28 |
| Turnover-Worthy | 22 | 12 | 19 |
- Review film: Williams' 2022 USC vs. UCLA "Hail Mary" (42 yards, November 19, 2022) vs. 2025 Bears TD to DJ Moore.
- Track EPA growth: From -69.4 ('24) to positive late '25.
- Monitor 2026 camp: Arm strength still elite, per May 12, 2026 PFF grades.
Analysts project Williams as a top-10 QB by 2027, blending college flair with pro polish, if protection holds.
