Tom Allen has been a breath of fresh air around Clemson's football program as he injects authority and energy that were lacking before Dabo Swinney hired him from Penn State.

He's already gone back and watched plenty of film from last year, including of the first two practices. He didn't like what he saw.

Allen goes in-depth on his task at his new job and how it differs from the objective he had a year ago when he took over the Nittany Lions.

Will Heldt made a big splash by signing with Clemson out of the transfer portal, and he's made an even bigger one over the past couple months during intense workouts and practices. 

Bottom line after he won just five games the past two years at Purdue: He's hungry to win big, and that hunger has rubbed off on a group of returning players who have won a lot but not enough for their liking.
