Apparently, he has… Considering that my opinion is shared by the coaches, who are choosing to make him the primary focus at tight end (thus far) based on what they’ve seen from him in both practices and games.
Additionally, Mack was probably better at the “dirty work“ than anything else in 2017. He wasn’t great at catching the ball consistently or making plays down field (which was largely influenced by QB play) but his “Chain moving catches” and especially his blocking were the best parts of his game.
I like Kmet and Wright, a lot. Both have fantastic physical talent that should help us in the future. In fact, both should help us in 2018. But neither one has done even as much on the field as Mack has.
In fact, saying that you’ll go with either one of those two players because of what Mack hasn’t shown is logically inconsistent and backwards. He’s done more on the field, and clearly more and practice, not only producing more game stats but also enough practice work that the coaches have chosen to make him the primary focus.
In reality, there’s really no basis for your stance on Kmet and Wright over Mack… Not the other way around.
