Koroma is very good, but he is undersized and teams can exploit that. Dawe made huge strides as a walkon and overachieved as a 5th year senior. Kanuch is an excellent run blocker, but a mediocre pass blocker. The two SUU transfers got mixed reviews, but they were developed ala Dawe at SUU. None of them are even close to NFL talents.
Shoaf has some talent, but time will tell to see how good he becomes.
