USC tight end Rhett Ellison has been getting a lot of snaps at fullback as youngsters Soma Vainuku and Charles Burks continue to struggle with learning the position.
Given Ellison's willingness to block and his pass-catching ability, as well as the greeness of the new guys, perhaps this isn't just a "fill-in" time for Ellison. He brings plenty of the same skills to the position that the departed Stanley Havili did. Keep an eye on this situation through camp.
