I'm not convinced that McVay will come in and blow up the offensive skill positions in year 1. IMO the offensive line will have the most changes.
Well I'll put it this way Mojo...
McVay runs an offense known for its precision on routes. Jay Gruden's offense in general has been known for that even going back to Cincinnati. He's going to load up tape of the Rams' wideouts, then he's going to grab a trash can and puke in it until it's dry heaves.
Then he's going to let Britt and Quick walk, and bring in at least one good wideout that Goff can rely on. Probably will draft another wideout as well for that matter. So I don't know if that's blowing it up, but I'll add that if Tavon doesn't sharpen up his routes he won't be on the field, so can't really say anyone's safe.
This guy has expectations, not loyalties to guys he brought in. All bets are off on that IMO.
