leaving a school? That's a pretty serious allegation to be throwing around.
Of the kids from Utah, McKay Murphy and Likio Pope were walk-ons DT's who were never going to go very far at Utah, and Tyron Morris-Edwards had graduated and wanted more playing time than he was going to see this year. I find it difficult to see too much insidious behavior in their moves to Weber State.
Also, aren't there 2 BYU transfers on the roster this year? Tui and QB Billy Green?
