I think this rumor is completely bonkers too and can't possibly have any root of fact. However, it did make me think. If you were Detroit what kind of offer lands Calvin from you?
Especially after trading away Roy Williams. I have to believe that Calvin is about as close to untouchable, and it was already said that him, Avril and Sims would be "cornerstones" of the rebuilding process.
I guess in theory they could think that Crabtree would be there at
1.08 and he might be a comparable talent so if they can address other holes, but overall it seems very silly to me.
