For Collins, progress this winter was dropping 15 pounds and reducing his body fat to less than 20 percent of his total weight. The 6-foot-2 Collins now weighs 298 pounds and has more definition in his upper body, the product, he said, of explosive-repetition training. That explosiveness has shown thus far in spring practice. It’s Collins’ first spring with the Huskers after finishing his true freshman season with 12 tackles and two tackles for loss.
Take Monday’s one-on-one pass rush drill pitting offensive and defensive linemen against one another. Collins paired off against three linemen in reps, appearing to win each. One of them even came at defensive end, where Pelini said he might use Collins if depth at the position remains thin in the fall.
Then on Wednesday, Collins — along with sophomore Vincent Valentine — helped blow up several of the top offense’s running plays toward the end of practice. Kaczenski was coaching the line between each rep, clapping and exhorting his men to play with technique and ferocity. Collins said Kaczenski’s relentless style of mentoring took some adjusting to when he arrived on campus last summer.
