I misstated what I actually watched on Kroft to form my opinion on him when we first signed him; they were actually samples of team highlights that involved him, which gave me an idea of the type of player we were getting: a player with good hands and some quickness.
By a bit more wide open, I mean by resembling offenses who aggressively look to carve up the opposition through the air (ex., Saints, Chiefs, Buccaneers), versus passing a bunch with the intent of getting your young QB in a rhythm and throwing with confidence, while failing to establish overall balance and rhythm on offense in the process; I think there are a bit of passing plays in the Bills' playbook that lack big-play potential simply because of the sets used.
