Why?
Mock's are extremely random pre-March. Even after that, it's a shot in the dark. However, I enjoy them and think they're fun to talk about as well.
That player you speak up is ALMOST what we saw from Manny Lawson towards the end of the season. I utility guy, like Arizona's Deone Buchanan, that can do it all. Rex's defense needs versatility within its ranks, something that was obviously lacking in 2015.
