I think your jumping the gun here Merlin. Boras is a co offensive coordinator, essentially. He had to have a passing coordinator to help him out. Neither Boras or Groh are 'The Guy'. I dont think one year of the Rams offense showing improvement will make teams willing to hand either of them the reins. Even two years wont do it. Goff will get most of the credit and the OC running game and OC passing game wont get the respect around the league because neither is the main man calling all of the shots. Offenses have to have repeated success for several years or a knack for QB development and show some sort of innovation for an OC to be noticed.
I see this kind of discussion as the in-between-OTA-and-camp-madness type deal. I'm bored, and yeah there's nothing saying this offense will even finish above 28th or so and this is all moot.
Thing is when you have an offense that has been this bad for this long, however, turning it around would be a big deal. If that happens Fish is going to have to demonstrate an ability to keep the right guy. For example what if the passing game explodes and our offense finishes top ten in scoring? Other coaches are going to be all over Groh for their OC position which is a positional upgrade and right out the gate the success results in being picked over. Happened with Seattle, and you see it with teams that rise with unknown coordinators and positional coaches over and over.
And going back to what I said earlier... If it happens it's a good thing. But I'm also at that point concerned about whether Fish has that clout to keep a hot candidate around like you've seen some other coaches like Shanahan do with Kubiak. If Fish finds himself in that boat there's real risk of him losing Groh to an OC position (he will not stand in the way of coach promotions IMO) or Boras killing it in an interview and getting a HC gig. Worst case would be Boras getting the gig because then he might well bring Groh with him as his OC.
Just spitballin here. And to be honest I think I'm still shell shocked by the Schotty hire. Fisher's "feel" for offensive coaches really worries me, so I suppose now that I think he finally got it right I am looking for a way for it to go bad, idk.
