2. Sean McKeon
The Cowboys don't have huge top-end talent at tight end, but the position is certainly deep in Dallas.
That became even more true when John Stephens Jr. started to really impress in training camp, but even with Stephens suffering a season-ending injury, Sean McKeon isn't going to be able to crack the 53.
And rather than listing them all individually, you can also replace McKeon's name with Princeton Fant and Seth Green. It's just that McKeon is the closest in that trio and still won't get the nod.
Carrying four tight ends is a lot on an NFL roster, and you realy need a convincing reason to do so. McKeon does differentiate him some from the rest of the Cowboys depth by thriving as a run blocker, but he just doesn't have the upside to be worth keeping around.
Luke Schoonmaker is obviously the future, Jake Ferguson is a solid option and Peyton Hendershot has been a serious standout this preseason.
The 25-year-old McKeon has caught just 6 passes in three NFL seasons, and we simply don't need to devote the roster spot for a guy who essentially serves as a sixth offensive linemen. If we want that kind of run blocking in short-yardage sets, we're better off just going with an actual lineman.
