There's pro's and cons to both sides of this trade.
Motter is an under-used WR with a very favorable contract. It will be interesting to see what he can do in the Arizona offense. To me CB Sakamoto is more suited at the safety position with that slow accel, decent size(could use a few pounds and poor m2m coverage. He's been getting burned at the CB position. And the teams swap picks. I think the 2nd rounder sways the trade in favor of Tampa Bay.
