Even those like Perry-Ellis and Parker, if they went on missions before there freshman years, wouldn't be as great either. Lack of conditioning is a huge thing and, as with Emery and Seljaas, the longer the season goes the more it effects players.
In fact, many here are looking at Mika as the answer inside next year, but I fully expect that we'll seem him struggle next year, as he deals with a lack of conditioning caused by his mission. This really is a huge issue that very few other schools (other than maybe Utah or USU for a few players) really has to deal with.
