I sent you a PM over PSN.  I think it's a very strong team.  My defense isn't any good so I might not be the best test-case.   Most people are going to be able to march down the field on me, just like you did.
The only thing I was getting really frustrated about was the way you kept converting 3rd downs, no matter the distance.  But you have some good receivers and a 99 QB, so that helps.
I'm not sure about your defense.  I only called maybe three or four passing plays the whole game (until the 4th quarter when I had no choice), so I can't really comment on that.  The Flexbone is fun, but I have a feeling it's going to suck against other human opponents.  The passing plays out of it aren't very good.  It's basically a lot of slants and curls, but nothing special.  I don't know about you, but I can never get a HB Pass or WR Pass to work, and my playbook's packed with those.
