Better is a relative term.
I think the Chiefs improve in the running game. Hunt is going to add that elusive, patient, Priest Holmes-like runner that the Chiefs need to offset Ware's hammerhead style.
In the passing game, I really don't think we'll see a change in production. Hill will get more targets, and I'd imagine Albert Wilson will return to getting the targets he saw in 2015.
Defensively, I think a healthy return of Mauga and the addition of Logan really helps the rush defense. I think the Chiefs could feel the loss of Howard, especially as a guy that could slide down to the nose. They don't really have a guy that can do that otherwise. I don't really see an adequate replacement for DJ yet, but I have at least moderate faith in Wilson that the position doesn't implode. I don't see a fall-off on D. A healthy Houston improves everything.
