Let me start by saying that this news is absolutely hilarious. The only people that shouldn't laugh when they read this is Washington Redskins' fans. Hell, I would argue that even they should see the self deprecating humor in a self proclaimed "draft expert" being entrusted with extinguishing what has become an organizational dumpster fire. Sometimes funny is objectively funny, and Mike Mayock running an NFL team solely because he's pretty good at doing the athletic equivalent of shooting craps is just that.
That being said, I'm not so sure he wouldn't be a fine hire. If John Lynch and Magic Johnson have taught us anything it's that putting unqualified people in positions of power is all the rage. You could argue that the particular unqualified person in question isn't due a promotion with how mediocre he's been at his current occupation, but the fact of the matter is that his current occupation is inherently impossible. His job is easy in the sense that their is no consequences to being wrong, but it's exceedingly difficult in the sense that there is no way to be right with any consistency. You can only be so reliable when you're asked to judge 18-22 year old kids on every single measurable other than their dick size and watch them beat the crap out of lesser competition in order to prognosticate what they'll be capable of as they mature and grow into their bodies. Seeing as he's been on my television every offseason for as long as I can remember, I have no choice but to assume that Mike Mayock is a better talent evaluator than most, and that's an unbelievable important skill to have as a General Manager.
The problem here is that the Washington Redskins don't have anywhere near the league-wide respect to make a move like this without instantly getting roasted. You know the benefit of the doubt that the New England Patriots have earned? Picture the exact opposite and that's what's given to the franchise that just fired their GM for being either drunk, missing, or incompetent for months on end. I don't know if the poor man's Mel Kiper will make a passable executive, but I do know that hiring a guy that most people look at as a punchline isn't going to help an organization clean up it's reputation as a clown show.
In reality, Mike Mayock is probably too smart and accomplished to accept employment from Dan Snyder, but tell that to the person picking apart every scouting report he's ever botched in head scratching fashion.
