He shouldn't be telling the players anything. The players fought for each other and won the game in spite of his rookie mistakes. Him and Grantham sucked all game in every way from schemes to decision making. Embarrassing.
Completely disagree
During the timeout you coach your kids on what to do
He made a bad decision on the 2 pointer, and seemingly failed to tell the kids what to do if they run fir the first down. Big mistakes
Players slide to clinch games all the time, they also should know better
Overall, doubt Mullen makes those mistakes again. Go for two when down five after a score, but not that early
