A chill has overtaken college football fans. Not from the increasingly approaching winter weather, but from the fact two months of action has already passed us by and the number of games left this fall is dwindling. No question, it’s a spooky feeling — just in time for Halloween, no less.

But despite the crisp bite late autumn can bring, a number of hot shots, blazers, and fiery playmakers still demand we enjoy these final weeks and celebrate their accomplishments.

And as far as our On3 Impact Rankings go, let’s shout out some of those standouts from Week 9 who keep sizzling on the stat sheet and impressing on tape!

Impact Riser of the Week: WR KJ Duff, Rutgers

Previous Rank: WR 61, Outside Top300
Current Rank: WR 29, Player No. 260

KJ Duff dominated the Boilermakers’ sorry secondary on Saturday. On just 6 catches, the 6’6 sophomore was responsible for 241 yards — 50 more than anyone else in college football this weekend. All of them were needed for the Scarlet Knights to put away pesky Purdue. All but one of his connections resulted in either a fresh set of downs or points. And, all but one of his snags gained at least 30 yards. The crown jewel of the afternoon was his longest play of the day, a 72-yarder off a Yankee Shot “Hiccup”, where he worked himself wide-the-hell-open.

Now inside the top30 at the position, Duff’s potency is tracking to be elite stuff. Of the 35 qualifying wide receivers with at least a 16.0 average depth of target (or how far downfield one is when thrown the ball on average), his 54.8% First Down+TD Rate rocks the gold medal. And for what it’s worth, that clip is top25 outright. Pretty impressive for someone originally recruited to be a tight end.

No. 2: EDGE Princewill Umanmielen, Ole Miss

Previous Rank: EDGE 32, Outside Top300
Current Rank: EDGE 17, Player No. 113

You might have heard John Mateer didn’t have his sharpest day facing Lane Kiffin’s Land Sharks. Prized portal win Princewill Umanmielen was a major catalyst making the Sooner’s swashbuckler uncomfortable and providing key impact plays. He tallied 3 stops, 5 hurries, and 2 sacks — making Saturday his first multi-sack effort of his career. It was also the fourth instance with at least 4 pressures and multiple stops this season.

Just outside the Top300 last week in our Impact Rankings, Umanmielen is now flirting with cracking the double-digits overall. You can thank that aforementioned consistent disruption as to why. Exiting the weekend, his 11.0% Havoc Rate exiting the weekend is the 13th-best mark among Power4 edges with at least 200 snaps.

No. 3: RB Jeremiah Cobb, Auburn

Previous Rank: RB 31, Outside Top300
Current Rank: RB 19, Player No. 231

While facing Arkansas’ dismal defense is usually a boon for any opponent, Jeremiah Cobb’s stock is at an all-time high following Hugh Freeze’s realization Auburn’s best path to success lies within its ability to pound the rock.

On his second +100-yard effort in as many tries (and fourth of the year), Cobb rushed for a career-best 153. His 717 yards ahead of Week 10 are the 8th-most in the P4 and only trail Ahmad Hardy within the SEC.

Adding extra mass to his frame has helped maximize one of the best areas of his game: Limiting negatives. Cobb has only surrendered 2 tackles for a loss so far in 2025. And on the 14 instances with initial defensive contact behind the line, 9 carries have generated positive yardage. His 64.3% clip is top4-worthy within the SEC; as is his 1.7% Negative and 54.7% Rushing Success Rates.

No. 4: RB Noah Whittington, Oregon

Previous Rank: RB 74, Outside Top300
Current Rank: RB 48, Outside Top300

Noah Whittington is the clear hot hand within Oregon’s running back room. Over the last two weeks, he’s logged 222 yards, a 32% Broken Tackle Rate, a 20% Explosive Run Rate, and a 3.9 YAC average. PFF presently grades him as the 11th-best P4 RB with a 85.7 score. But if you’re still stuck on the old way of measuring ball carriers, you’ll be happy to know his 8.5 Yards/Attempt is the 2nd-best mark among guys with at least 50 attempts this fall.

No. 5: WR Isaiah Satenga III, Oklahoma

Previous Rank: WR 58, Outside Top300
Current Rank: WR 44, Outside Top300

The Sooners’ roll has slowed considerably since John Mateer’s hand injury. Despite that, Isaiah Satenga role of playmaker for Oklahoma’s offense has solidified. He was the clear go-to against Ole Miss, catching 6-of-11 targets for 131 yards and a score — Satenga’s second +100 yard, 1 TD game in conference play.

The Arkansas castaway has now fielded the league’s 3rd most targets (66) for the 5th-most catches (43) and yards (624). The track standout has not only excelled running around and away from defenders but making them miss, too. Satenga is presently 1/8 WRs to average at least 8 yards after the catch with over 10 broken tackles. Speaking of, his 14 missed tackles forced are tied for the 9th-most.

No. 6: EDGE Nathan Voorhis, Ball State

Previous Rank: EDGE 87, Outside Top300
Current Rank: EDGE 63, Outside Top300

Nathan Voorhis productive season continued over the weekend. Even though Ball State tacked on another loss, the hyperactive edge recorded six stops and a sack. It was the second-straight game with a QB takedown and his fifth in October, which matched his September total. Only 5-star David Bailey has more ahead of November.

Though the sacks rosescent his profile considerably, the Bryant-transfer is more than just a pass rush specialist. Voorhis’ 57 impact plays (havocs + stops) are the 10th-most at the position and top20 among all defenders exiting the weekend.

No. 7: DL Jason Hammond, Virginia

Previous Rank: Not Ranked
Current Rank: DL 60, Outside Top300

Jason Hammond has been a steady and reliable interior for Virginia’s defensive front. And, he arguably played his best game when the Cavaliers needed to grit one out against Bill Belichick’s squad in overtime. The St. Thomas Aquinas product had 3 pressures and 3 stops. Over a tenth of his snaps have yielded an impact play across the first two months.

Though there’s still loads of room for growth, Virginia’s postseason bid requires a bevy of players like Hammond to punch above their weight and add value. If he keeps this up, the d-lineman will be in discussion for all-conference honors.

No. 8: S Wydett Williams, Ole Miss

Previous Rank: S 41, Outside Top300
Current Rank: S 26, Outside Top300

Wydett Williams was an unheralded addition to Pete Golding’s defense. But despite the lack glitz and glamor, he’s quietly emerged among the SEC’s top coveragemen. Against Oklahoma, the former Louisiana Monroe safety only allowed 16 yards on 6 targets and broke up a couple of passes. His 74.2 PFF grade was the highest against a P4 opponent in his career.

This fall, Williams has managed to hawk over a fifth of his opportunities while holding opponents to a 3.1 yards/target, the lowest figure among conference safeties with at least 150 coverage snaps. And on a per-snap basis, the Rebel’s 0.35 clip is top25-worthy among P4 players at the position.

Blue Chip Shoutout: RB Isaac Brown, Louisville

Previous Rank: RB 6, Player No. 41
Current Rank: RB 4, Player No. 19

We at On3 expected massive things from Isaac Brown this fall. After all, he was a top50 player for us this preseason. His play after returning from injury illustrates why we and many others gush about his running style and ability to rack up a whole bunch of yards. Over the last two games, Brown’s 314 yards are the most in the P4. Moreover, his 68.9% Broken Tackle and 31.0% Explosive Run Rates in that span are astronomical. No running back boasts a better Yards/Attempt than his 8.8 figure. And, no major conference ball carrier can top his mighty 5.6 YAC average.

Though maintaining that output will be extremely challenging, there’s little doubt he’s among college football’s elite players when fully healthy. And since now that appears to be the case again, Brown’s boost into the top20 in our Impact Rankings was an easy call.
