Texas stays No. 1 as Week 4 upsets reshape the playoff race

Texas preserved its No. 1 ranking by edging Tennessee 20-17, powered by a defense that recorded 10 sacks and Colin Simmons's five-sack performance. Florida upset Ole Miss, Iowa won on a last-second play and Wisconsin rallied, while Dante Moore's injury adds uncertainty to Oregon's playoff outlook. Texas's 11 penalties, Tennessee's protection failures and the growing upset wave are reshaping conference trajectories.
