I remember hearing that the Eagles tried to get Shady last year before trading for Ajayi. If thats the case and the price tag is too high for Bell, it wouldnt shock me to see them try again. They could grab McCoy for this year and try for Bell in the off-season.
That said, he means much more to this team this year than a 3rd or 4th (at most) in next years draft would help out. Despite his off field distractions (to himself more than team) he's stepped up and really been a leader. He's not going anywhere this year.
