Lamar Jackson perplexed that other teams know their plays

Defenses may sniff out a play or two during the course of a game, but what good defenses do is know the opponent's tendencies based on formations, game situation, etc., and they do that through film study. Case in point: Porter's pick-6 in the SB. Film study told him what they liked to do in that situation, and sure enough, they "ran their favorite play," as Simms commented on the replay.
