I think at this point Allen can diagnose and find the weakness against any defense. It happens to all great QBs at a certain point. Leading the first 30+ point game scored against KC in something like 25 games is a testament to this. Spags threw everything he could at Allen and none of it really confused him. Also the fact that he hasn't thrown a single WTF interception this year, as in all of his interceptions have been reasonable decisions based on the coverage shown. And I'm sure that's why defenses are showing us more man than any other team. They figure they have better odds of stopping our pass catchers from getting open, than they do of stopping Allen from diagnosing the right throwing window.
