Sorry, my response was more just a general response to John's comments, I don't really mind the premise of the thread...
That said, you had me right up to:
Why do you feel he's in over his head? By all accounts he just led a successful draft and players seems to be bullish...

Google something like "What makes Sean McDermott a good coach" and read some the articles. At this point we're going to have to wait for the season to see how he does, but IMO, you can't help but be at least a *little* optimistic.
