I think Carolina could justify a 4th. He'd be a massive handful to deal with when Cam is preventing one end from collapsing down, he'd complement McCaffery well, and he'd limit the usage on McCaffery.

I could also see Howard as a really good fit as a backup in Dallas, as the guy in Houston or Indy, or as a complementary piece in Minnesota or New Orleans. Just because RB isn't highly valued and Howard isn't the modern archetype at the position doesn't mean he can't play.

He's a proven inside runner with good vision, pad level, and understanding of his blocks. I guess if teams had concern about his fit in a power scheme then you could limit those destinations a little, but I think he'd be fine in any blocking scheme.
