Based on the bad coaching decisions and strange post game press conferences, I think I know now what Biff is rolling
Successful - improvement across the board.
What does that look like? 350-400 total yards per game average on offense. 25-30 pts per game on offense. Under 350 yards per game on defense. Under 25 pts per game on defense.
This would lead to a minimum of 6-7 wins and a competitive bowl game.
8-9 wins and a bowl win (9-10 total) is what I would like to see. However, the list above would make it a successful season.
