Isaac Brown
Isaac Brown was the No. 1 running back in the transfer portal. Texas, Notre Dame, and Miami all called. He stayed at Louisville -- because he's the offense, and he has a statement to make.

The story
Two seasons, 2,057 rushing yards, 18 touchdowns -- and in 2025, 884 yards on 8.75 yards a carry in just nine games, one of the most explosive per-carry marks in the country (our explosiveness metric grades it in the 98th percentile). When he entered the portal in January he became its No. 1 back overnight; then he negotiated a new deal and came home, telling Louisville he wanted to "make a statement." Now the Freshman All-American turned third-team All-ACC pick is the undisputed centerpiece of Jeff Brohm's offense for his junior year. The forward stakes are an All-America case and a draft climb: a back who turns the corner and is gone needs only volume and health to be the ACC's premier home-run hitter. For Brown, 2026 is the year the highlight reel becomes a résumé.

How he plays
Play style
Brown is a home-run hitter in a 5-9, 190 frame -- built low, built to disappear around the edge. The explosiveness is the headline and it's real: 8.75 yards per carry in 2025 (up from 7.1 as a freshman), which our play-by-play grades in the 98th percentile, paired with an 82nd-percentile success rate that says the booms don't come at the cost of steady gains. The earliest scouting read (an SI breakdown, from his recruiting days) flagged exactly what the tape now shows -- "elusive" and "very good at avoiding contact," with a specialty "running to the boundary and turning the corner" off an "above-average first cut" -- plus real value as a receiver "out of the backfield, especially on swing passes." The honest note is the frame: at 190 pounds he's a speed-and-space back, not a between-the-tackles grinder. Give him the edge and a crease, and he's one of the fastest players to the perimeter in the sport.
Our classifier reads him the same way: hits the crease and outruns the angle.
