I'm not advocating that we try to trade for Bosa. First, the Dolphins don't need another highly paid defensive lineman. We have too much money invested in the position to brook another signing. Even if we did want Bosa, he can't move until draft day 2017.
No, the move here is to capitalize on our being long on DE's. The Chargers, who are desperate to win the west in the face of stadium/relocation pressures, are now short a major piece. So it's time for Miami to make a forward-looking deal and trade a DE for picks.
We are likely to cut either Fede or McCain and certain to cut Dion Jordan (see my earlier piece here.) Why not see if San Diego will part with a pick in next year's very deep and talented draft?
We need to turn their desperation into a chance to draft a useful linebacker or corner next year. It's time to profit off of another team's need before roster cuts force our hand.
