Solomon wasn't much of a dual threat guy last year. He was more so as a freshman and he may not be as much going forward if he continues to struggle with being afraid. Basically his words. I think those concussions have made him less confident.
And BYU has plenty of speed. I don't know why you said Langi being at end is a disadvantage. It's quite the opposite. Langi is going to be what helps slow them down on the outside. He and Tautu are fast rushers. Warner is fast. Pau'u is athletic and will be all over the place.
I'm not concerned about BYU's speed. The only concern should be whether or not they've improved their discipline and tackling. Langi will be one of the most athletic guys on the field at all times so that's not his issue. BYU has struggled with tackling the last few years and guys can't break down to save their lives. I think that culture will change.
