FTFY
Counting signings separate from the trade as part of the trade is kinda silly. Otherwise we should say that we picked up Harvin, Felton, and Clay in the trade as well.
Why would he come here?
He passed on multiple offers to sign with the Eagles. Do you think he would have come here? Do you think Whaley would have signed him since we were still showing interest in CJ at the time?
IMO, it's safer to give up a guy we arguably didn't miss last year*, to guarantee we land a stud RB, than it is to play the guessing game of free agency. Let's say we float an offer to Murray and he passes it up, and CJ still goes to NO. Where do we stand at that point?
* - Not saying Kiko sucks, just that we survived and succeeded without him last year. He's a good player, just we ended up being ok without said good player.
