It’s not often that the Pittsburgh Steelers carry four true tight ends on the 53-man roster. In fact, the only time that I can recall it occurring, it was merely procedural and lasted a couple days during the start of the 2013 season, because Matt Spaeth had to be on the 53-man roster in order to be eligible to be placed on the designated to return list.
I have argued earlier this offseason, however, in favor of the idea of at least exploring the idea of carrying four true tight ends, or a variety of factors, the primary of which being that they do appear to have a decent group of tight ends to choose from this season.
