Well the run game definitely doesn't suck when he is not there. Mostert was still breaking big runs. But the reason why it may not look as good is because Dwelley is the back up. He's more a WR than a TE. His receptions skills are good, but his blocking is meh.
There will be no discount. You see Tartt ain't giving one.
Mostert was fast enough that he didn't need blocks to develop. I don't think we have that kind of runner on the team. Mitchell is fast like 4.3 or 4.4 fast but I don't see that burst.
Also... again, how the fukk did Kittle get hurt?
