Hell, if he needs his guys he can have, Fergueson (love ya big guy but we're managing pretty well without ya), Carpenter (maybe Bill can actually justify playing the guy), Glenn (barring a miraculous recovery and a lights out playoff performance), Jacob Rogers (I'm sure he's sitting around waiting for a contract).
All joking aside, Parcells is going to come hard at some of our guys. It makes sense. In the same position any one of us would do the same thing. Going into a new job you want to surround yourself with as much familiarity as possible. There's a chance he goes after some of the Pats coaches (OC) or Jets guys, or even Weiss and Crennel's staff/players also. He's done it everywhere he's gone.
Here in Dallas he pretty much just went after former players. Sporano was coaching in college. Payton was just demoted from play-calling. I don't believe Carthon was coaching anywhere. Not sure where Haley came from, but I'm almost positive he'd never worked with Bill before. With the exception of Carthon, I don't think Bill had any other work experience with any of them. There's no absolute certainty that Ireland or ANY of our coaches are going anywhere.
One thing is for sure, IF Ireland leaves, Jerry is going to make sure he's compensated.
