LSU quarterback Joe Burrow had a dominant performance at Texas on Saturday night. Burrow and the 2-0 Tigers are looking like serious College Football Playoff contenders. The former Ohio State QB should be a Heisman frontrunner, too.Oklahoma quarterback Jalen Hurts, meanwhile, continues to put up dominant stats leading the Sooners. Clemson’s Trevor Lawrence looked good in the Tigers’ big win over Texas A&M, too.College football analyst Barrett Sallee has released a new Heisman Trophy top five following Week 2. The college football writer for CBS Sports has Burrow leading the race:My Heisman top five right now:1. Joe Burrow2. Jalen Hurts3. Tua Tagovailoa4. Justin Fields5. Trevor LawrenceOutside looking in: Jonathan Taylor, Jake Fromm— Barrett Sallee (@BarrettSallee) September 8, 2019It’s tough to argue with that top five right now. No one has a better win than LSU and no one has a better individual performance on a big stage than Burrow in that contest.There’s a long way to go, though.The Heisman Trophy picture should change a lot between now and December.
