The take from BDTW and Ballz, edited for clarity and brevity: Miller is a stiff who can only play guard, but Oregon promised he can play tackle. If Washington tells him he can play tackle he'll go there. He's also not a real commit, is going to want to take all his visits. Now Washington has a chance at Suamataia who will see that Oregon took other players on OL and will surely re-consider Oregon.
Ballz is going to be right about an Oregon recruit one of these days. It'll be glorious.
