Yeesh, this thread got crazy...
IMO, peple aren't overly critical of EJ becase he's black, they're overly critical because we live in an age where everyone is a critic. What's worse is we live in an age where if something isn't "the best ever" instantly, it completely sucks and has no chance of growing, or growing on you (athletes, music, movies, art, whatever).
Fwiw, I've worked with professional action sports athletes for years now - guess what? They tend to get better with a little experience and time to grow. Shaun White wasn't always the best snowboarder in the world, when he first went pro he was just a kid trying to learn his way.
Obviously quite different than a high draft pick QB in the NFL, but man, the armchair Internet critics that drone on and on about how they're right, just get old, IMO.
Just because EJ isn't great now (or, more to the point, helped do us in last week), doesn't necessarily mean he's terrible or doomed to lifelong failure.
