The thing I keep mulling over with Christian is he fills 3 needs...RB, returner, and slot receiver. It is very possible he provides more all purpose yards than someone like Fournette.
And Solomon, in spite of what some here are claiming, looks to me as the clear number 2 DE in this draft pool. Go back and watch what he did at Stanford. The guy was an effective rusher inside and outside, and was probably the best run defender of all the DE prospects.
