of it, but I don't think the RB position will struggle as much as you imply. It's pretty much the same group as last year (minus Ula - which sucks cause he's a beast). With 1 more year of experience and a better system, they should be solid. Not Jamaal Williams, but good.
I predict Squally will have a solid Senior year with 800-1,000 yards rushing. The rest of the RB committee will contribute in good ways (e.g., Hoge and Fonua catching some passes out of the backfield).
I really hope Ula comes back next year. If he can hold onto the ball, he's a slightly bigger, faster and strong Harvey Unga. He will be a beast. But given our history, he'll head up north and then run all over us for the next 2 years. I hope not, but we'll see.
