Behind a gritty quarterback, a dominant third-down performance and a defense that made just enough plays when it mattered, No. 17 Alabama knocked off No. 5 Georgia 24-21 on Saturday night at Sanford Stadium in another memorable showdown between two of the SEC’s most decorated programs.The Crimson Tide entered the fourth quarter clinging onto a three-point lead but was on the ropes early in the frame when the Bulldogs made their way down to the Alabama 8-yard line and needed just one yard on fourth down to keep what looked like would be a scoring drive alive. But Alabama’s defense stopped the Bulldogs for a loss of three yards and held on, as neither team scored again.Facing a critical third-and-5 to seal the game with just under two minutes to play, Alabama quarterback Ty Simpson hit Jamarion Miller for seven yards on a night when Simpson rose to the occasion and offensive coordinator Ryan Grubb kept Georgia on its toes all night with creative play-calling.“We got an extra week,” Kalen DeBoer said of Grubb’s creativity, which included throwing a screen pass to 6-foot-7, 366-pound offensive lineman Kadyn Proctor to set up an Alabama touchdown in the second quarter.“(We went) out and executed.”
