This was MacEntee's first experience with his feet to the fire and he wasn't ready. I doubt that he'll ever turn into Troy Aikmen but I remember Aikmen looking every bit as inept his rookie year with the Cowboys. He rushed too many throws (both passes that McCombs dropped were horrible passes, the first was drilled, on a line a bit too low and a bit too far in front of him, the second, high and behind him) and began worrying about pressure that wasn't yet there. This was however his first real game action against an FBS opponent. If the staff is ready to toss him to the scrap heap already we will never have a competent QB.
I don't know if Mac will ever be anything more than a QB who will look great when everything is going well (oline blocks all defenders, no third anmd longs, no dropped passes) but earlier this week, half of this board was convinced he was clearly the best QB on our roster last season, now many of the same posters want him benched. It doesn't work that way.
