I think the Ingram suspension showed that Kamara isn’t our #1 back. Number 1 on the depth chart sure but I don’t think he would hold up later in the season and playoffs without another legitimate threat to share carries with. By game 4 last year he was getting winded and just didn’t look like he was having fun anymore. He also tweaked his ankle a bit if I’m not mistaken.
It’s no knock on Kamara, he’s a rare talent in this league but there needs to be another back on the team that defenses are forced to respect.

As for MaCoy I’m sure he will be fine and will be legit from day 1 but to say he is going to step in and take the place of a Pro Bowl center without a drop off is a bit much. He will have his struggles. Struggle could lead to Qb injury. That cannot happen.
