A successful modern NFL offense dictates that a team possesses not only one star or good starting tight end, but depth and compliments behind him as to offer offensive versatility. Some of the league's top offense's in the last two seasons from the always relevant Patriots and Rob Gronkowski, to the Chiefs and Travis Kelce, all either had a tight end who could take over a game, or multiple solid options that offered contrasting valuable skills.
It's by no coincidence, that the latter two years of the offensively inept John Fox Bears era in 2016 and 2017 barely featured tight ends.
