If Babcock signs they will gladly let Blashill talk to NHL teams and get draft picks or whatever in return. That's why Blashill was given good money and term to stay around, it's either NHL with us soon or it'll be somewhere else but at least we'll get compensation in that scenario.
Yeah, I agree with this. They extended Blashill's contract to keep him around in case Babcock leaves. I don't think Blashill is 100% the guy if Babcock leaves, Holland will interview several guys and go through the whole process, but Blashill is certainly a favorite for the job.
If Babcock stays, or the Wings hire someone other than Blashill, there is no doubt that the Wings will let Blashill interview for other NHL head coaching jobs. If the head job in Detroit is not available to him, why force him to stay in the AHL? Yes, he is under contract with the Wings, but they won't force him to stay in the AHL for 2 or 3 more years, how ever long is left on his contract.
