I don't think this means anything other than McVay might wish to get some real experience behind the microphone to see what it's like and if he is any good at it. I think a lot depends on how the Rams do this year. If they are very good and make a deep playoff run I would expect McVay to come back and try to win another ring, especially if Stafford comes back.
Maybe this is a good chance to get Aubry Pleasant some head coaching experience. Maybe the Rams are trying to give the guy some experience so some other team will draft him and they get another set of 3rd-round comp picks. Either way, if McVay chooses to retire from coaching, I have the utmost confidence that Les Snead will find an excellent replacement.
Sometimes I don't think Les Snead gets enough credit for the job he's done, at least from the league's standpoint. Let's go back a few years... it was Snead who convinced Demoff and/or Kroenke to keep him after firing Jeff Fisher. Then he hires a 30 year-old "offensive assistant" with no head coaching experience who gets the team in the playoffs the very first year. In addition to that, Les brought on 35 year-old Andrew Whitworth to solidify the LT position, Robert Woods, John Sullivan, Nickell Robey-Coleman and Sammy Watkins. The team went from basically last place to first place in almost every offensive category. Then the team reaches the super bowl in 3 seasons and wins it in 5. It doesn't get any more successful than that.
And most important (to Stan anyway) his success has helped improve the Rams standing in the league, in Stan's net worth, and popularity in the Los Angeles area 5 times over what they were worth before.
For an encore... Les drafts late-round prospects that turn into incredible rookies/stars after a disaster-filled year when the team didn't even have a 1st or 2nd round pick and no one, including me, expected them to be any good and especially not make the playoffs. This year's draft appears to be another incredible draft for Snead. Maybe even better than last year, if you can believe that (we'll see). I'm sure McVay has Snead's ear in the draft room and is certainly a "decision-influencer", but I think Les makes the final decisions on most picks. After all... it is Les Snead's team who scouts college players every year. And now, it looks like Snead has done it again in this year's draft. I swear... the guy is King Midas.
Bottom like is that IF/WHEN we lose McVay, I will be very sad. But I would expect Les to go find another gem in the football world. Who knows... maybe it will be Aubry Pleasant.
