Kupp's one problem was the key drops at bad times. The one that lost us the game at home vs Seattle, the one that basically erased a key TD early vs the Vikings, and even in the Tennessee game the one that he dropped on a critical third down.
But I think that last game vs the Titans he showed he moved past that. That TD he caught was phenomenal and won us the game, and IMO was a huge growth point in his young career. And IMO he's going to beast in the playoffs starting Saturday night vs the Falcons.
