Grier threw four touchdown passes — all in the first half — and No. 25 Florida upset third-ranked Mississippi 38-10 on Saturday night to give coach Jim McElwain a signature win in his first season in Gainesville. Grier was feeling so ill Thursday and Friday that the Gators (5-0, 3-0 Southeastern Conference) considered giving Treon Harris the nod. The freshman completed 24 of 29 passes for 271 yards against the Rebels (4-1, 2-1). Grier added two more TD passes in the second quarter, beating a third-down blitz with a quick slant to Brandon Powell. Florida's offensive line, which was widely considered overmatched against Ole Miss' vaunted defensive front that features Nkemdiche, gave Grier enough time to make reads and deliver accurate passes. The Rebels had four turnovers, missed a field goal early and settled for a field goal after getting to the 1-yard line while trailing 25-0. Vernon Hargreaves III returned the pick inside the 10-yard line midway through the fourth, but the Gators settled for a short field goal that got the celebration started. CeCe Jefferson returned Kelly's second fumble to the 1-yard line on the ensuing possession, and Jordan Cronkrite punched it in from there — long after most of the disgruntled Ole Miss fans had left the Swamp.
