McCown has played about as I expected, to be honest - he's an old vet who understands the game, and he's been blessed with crappy competition the last few weeks. He's a guy who will have runs - i.e., his lights-out performance for the Bears in 2013. He quickly came back to earth, however -- as he always does. He's not a great QB for a team that's behind, and I expect his numbers will be bad this week against the Pats regardless of the limitations of the Pats' secondary (I expect NE to utterly blow them out).
One thing I've noticed about the Jets - Kearse is a pretty good player. Ryan Matthews is essentially a poor man's Kearse (not that Matthews is a bad player or anything like that).
There is terrible blocking, opponents know what's coming, and they don't fear the Bills receivers - it's pretty simple. McCoy looks as elite in terms of speed/cutting ability as he's always looked.
