Apparently he played through back issues last season, (Walker), which, if he could fully recover from, could be considered a positive. Same goes for Shemar Turner. He played hurt most of the season. Something lower unit. Did not shut it down. This also speaks to his dedication.Well Caldwell is built more like a NT. Walker is too tall and has a small base for somebody of his size.
If we take Graham or Grant in the 1st, IMO, Turner in the 3rd, and Walker on the 3rd day, 4-5 range, wouldn't be a bad way to go.
