I agree even though, I believe it would be a good trade for Denver, Cleveland would have no benefit. Cleveland has a quaterback, or someone the think will be their quaterback. When trading Cleveland should try to get something they don't have. Whether they trade Quinn or Anderson, it makes no sense to trade a quaterback for another quaterback. Then you still have 2 quaterbacks with no one to catch the ball, it would be better to try to get a quality receiver.
Possible considerations:
Jets, Bucs, Vikings, Bears, Lions, Panthers, Jags. If I was the GM of the Lions, I would try to trade for BQ with a decent veteran, then trade my 1st overall pick and try to pick up a later 1st round pick and a second round pick. to possibility bolster the offensive line.
