If someone is drafting WR in the 1st round it could be interesting to get a 29yr old vet who should have another 5 yrs of peak performance left in him, instead of an unproven rook. I've seen some mocks have Bengals targeting a WR, I bet they'd at least listen.
Or like I posted earlier, Bears could be enticed into getting a deep threar for Cutler. I see Evans fitting in really well with their system and needs.
But if we did a trade, so what? We've just created a huge need at WR.
