Any player who is good enough will be featured enough to put up good stats. I have a lot of respect for Higs and what he does as an all-around TE. But he's not a difference maker, or hasn't been that, so he doesn't get play design where he's high enough as a read to get those stats.
Stick a younger Gronk or one of the current top TEs around the league on this roster and you can bet they'd be a top read in many situations, and high enough that they're gonna get catches and yards.
I'm really excited about the TEs this year btw. But the point of my post is really the business side, a look at the roster and the decisions that are looming and might be made sooner than later. Both positions have a lot of decisions looming, even though wideout is absolutely loaded.
