I think Detroit has already filled their quota of suspect dmen.

Why trade Wideman? It's not like he's signed long term or to a big contract.
From the interviews I've read he seems like a good locker room guy who knows his role and doesn't complain about it.
Also I thought it was cool of him to change numbers for Slaf last year, showing he's a team guy.
I know these are small things but, to me they matter.
