Not with the talent level we had, especially at QB. You might - and stress might - have been able to get wins over Temple and Memphis as those were losses by a combined 3 points. But no other head coach was going to make a difference in wins and losses on the other 6 games where we lost by an average of 28.1 points.
One could argue that with a different coach, we may not have even been competitive in the Temple and Memphis games, so that argument goes both ways.
But the bigger question is, why do you think winning 3 games - which is the now the acid test for your argument - an improvement since you entire argument is based on 1 win being less than 4 wins??
When I think you are being an insufferable blowhard with arguments that are weaker than North Korea's Bill of Rights, then you have really jumped the shark.
