I'll try:
I'm not gonna argue the validity of the shotgun issue because I honestly have no clue whether the guy's opinion holds water or not. But I do think that rationalizing poor pass protection by citing the offense's rank is off-base. In my opinion, the only reason Romo hasn't been sacked a heck of a lot more than he has is his ability to avoid it. Maybe if Romo had a clean pocket to throw from, as Brees seems to, the Cowboys offense would be #1. There may be something to the idea that Tony is holding the ball more this year, but I think there's more to the difference in the number of sacks taken by Romo and Brees than that.
I also think there's a reason that Romo is the most blitzed QB in the League that doesn't have to do with his ability to make reads and get rid of the ball. The first thing that comes to my mind is offensive design. Of course, there's a whole bunch of other stuff that could be causing this phenomenon, but I don't think it's dumb at all to examine the offense itself, formations, playcalling, whatever.
But that's just me.
