The Indianapolis Colts kicked off their first practice since Andrew Luck's sudden retirement on Saturday ... with 3 QBs all vying to take his spot.
Of course, Brissett has a tremendous advantage ... not only did he start when Luck was injured last year, but he's a pretty solid quarterback.
Remember, back in 2017 (when Luck was injured) Jacoby stepped up and threw for more than 3,000 yards with 13 TDs and 7 INTs in 15 starts.
As for the rest of the QBs, the war is on for that backup spot ... and NFL legend Jim Kelly thinks it's a hell of an opportunity for his nephew, Chad.
