I haven't been impressed with Patenaude so far, but I think it's worth comparing his first 4 games at Tech vs. the rest of his career as an OC and considering why there is such a disparity. He wasn't exactly beloved at Temple, but their offense scored 35 PPG. If he simply had no clue how to coach an offense to score points at all, you'd think that would have been evident prior to this season.
I don't think it's accurate to chalk up our offensive woes 100% to the scheme change or lack of talent, but I think those are much bigger factors than those who already want him fired are willing to admit. This isn't meant to be some ringing endorsement of the guy, though, as I'm sure there are innovative OCs out there who could have gotten more out of our offense than he has thus far.
