College football fans have jobs to keep them busy, children to raise, lives to live.We understand that it’s not easy to determine whether your team’s transfer receiver, who was a former four-star recruit but has posted only 353 career yards at two different schools, is any good. Or whether the defensive end who recorded 10 sacks last year on a bad Group of 6 team is ready to impact a Power 4 program.So with the FBS season kicking off on Saturday (the FCS opens play tonight if you’re eager for some football), The Athletic is here to catch you up on all the notable roster movement you might have missed or forgotten about over the past nine months. Here’s our transfer portal cheat sheet.Who had the best classes?LSU is the most fascinating program in college football — for many reasons. The program spent a ton of money to fire Brian Kelly, hire Lane Kiffin, assemble Kiffin’s coaching staff, and then build the roster to his liking.Kiffin’s first portal class at LSU was ranked No. 1 in the country, headlined by one of the best quarterbacks (Sam Leavitt, Arizona State), the top offensive lineman (Jordan Seaton, Colorado) and proven, productive players across the roster such as receiver Jayce Brown (Kansas State), defensive end Princewill Umanmielen (Ole Miss) and safety Ty Benefield (Boise State). Heck, LSU is such a popular transfer destination that players are trying to leave the NFL to play for the Tigers.While LSU may be grabbing everyone’s attention, Indiana is the program that’s holding last season’s national championship trophy. The Hoosiers brought in another strong portal class (second in The Athletic’s rankings). TCU transfer Josh Hoover is the headliner and will replace Heisman Trophy winner Fernando Mendoza at quarterback. Receiver Nick Marsh (Michigan State), running back Turbo Richard (Boston College) and defensive linemen Tobi Osunsanmi and Chiddi Obiazor (both from Kansas State) will also help.Transfer portal sleeper teamsRalph D. Russo and Sam Khan Jr.Texas aggressively addressed its flaws and built an impressive supporting cast around quarterback Arch Manning. Receiver Cam Coleman (Auburn) was the best transfer addition nationally. He boosts the offense along with talented running backs Hollywood Smothers (NC State) and Raleek Brown (Arizona State) and offensive tackle Melvin Siani (Wake Forest). Former Pitt linebacker Rasheem Biles was a quality addition to an already stout defense. These transfers have Texas fans expecting a deep postseason run.Miami was desperate for a quarterback and landed one at the 11th hour. Duke transfer Darian Mensah hopes to follow in the footsteps of Cam Ward and Carson Beck, who were transfer success stories for the Hurricanes. After signing Mensah and his fellow Duke transfer Cooper Barkate, a 1,100-yard receiver in 2025, Miami might have the most talented offense in the country.Texas Tech’s most valuable transfer addition, former Cincinnati quarterback Brendan Sorsby, fell through after the fallout from a gambling scandal, but edge rushers Adam Trick (Miami of Ohio) and Trey White (San Diego State) are two critical pieces for the Big 12 favorites.OK, those are all somewhat familiar names. Did any programs surprise this offseason?Oklahoma State hired Eric Morris and added 89 new players (transfers and recruits) in the offseason, including 19 from his former school, North Texas. Headlining that group is a trio of offensive stars — quarterback Drew Mestemaker, who led the nation with 4,379 passing yards last year; running back Caleb Hawkins, who rushed for 1,434 yards and 25 touchdowns; and receiver Wyatt Young, who caught 70 passes for 1,264 yards and 10 scores. The Cowboys’ portal class ranked seventh nationally.Kentucky ranked right behind Oklahoma State at No. 8, with new coach Will Stein bringing in nearly 30 transfers, including highly touted Notre Dame quarterback Kenny Minchey and offensive lineman Lance Heard from Tennessee.After four years as Oregon’s defensive coordinator, Tosh Lupoi takes over at his alma mater, Cal. He brought in a top-15 transfer class filled with quality skill players — including receivers Ian Strong (Rutgers) and Chase Hendricks (Ohio) and running back Adam Mohammed (Washington) — to support emerging star QB Jaron-Keawe Sagapolutele.
