Lesser players making big plays are still lesser players. This is more widely accepted in other sports, where lesser players can go on hot streaks (See Jackie Bradley, Jr. and his batting). Also, see 2007 helmet catch for an excellent NFL example. David Tyree will always be a Giants hero, but that doesn't make him a great player. As a 6th round pick, he'll never be a bust, but he had fewer than 60 catches in his entire career.
I get the sentimental angle. I've probably bought into it numerous times over the years, too (Hell, I've probably bought into and used the very same argument you're using here), and I'll fall for it again in the future. But, if we're going to be as neutral as possible in our analysis, we then get to BB's "It is what it is". Michel's been a bust, to date.
