While it is a compliment of an extraordinary nature for McVay to virtually have to rebuild his staff every year because other teams feel like the Rams staff are always among the elite at their jobs, it makes life awfully tough for McVay and the team in general.
I think there ought to be some kind of NFL rule that any OC or DC hired away with a promotion, who has served less than 3 years with his current team, gives the team that lost that coach something like a 4th round pick (this is in addition to any of comp like the 3rd round minority hire pick).
