Former Colts OLB Phillip Wheeler, one of the Raiders’ key free agent signings, has impressed Dennis Allen with his athleticism and versatility. “He’s explosive, he’s got speed, he’s got some rush ability,” Allen said. “When we play some of our zone coverages, our Covers 2’s and stuff that he did in Indianapolis, he really excels at that. Being able to use guys like that, that have that type of athletic ability, where we can move him around and do some different stuff, I think that’s going to help us.”
