Does Glennon Play if We See Another McCown Blooper Reel?

I couldn't believe what I was watching last week unfold as McCown through two of the worst ill advised passes in recent memory.  I couldn't help but think back to last year when Glennon was the starter.  I simply cannot recall a single pass he threw last year that was as bad as those two.  Maybe there were...I can't remember them.  I still see those two passes by McCown in my head, and they will live on through NFL Films Blooper Reels.If McCown comes out of the gate today with the same results as last week, does Lovie have any choice but to bench him in favor or Glennon, or does Lovie stick with McCown?  Mike Glennon is simply a better QB than Josh McCown.
