He was waiting on Travis Decurie who was in the running for OSU. Now he can pick the school that he wants to attend. WSU offers PT which is big, and UW offers playing with his Cousin also a PG next year. But UW has no fewer than 3 PG's currently on the roster. So his PT will be limited unless he playing some SG which he could do.
Also the system they run requires more wings than true guards as one big is usually outside so rebounding requires a nice sized wing which they have several players that can do that.
Hay wouldn't surprise me to see Rorie at WSU or at UW. Heck even maybe back at Cal hard to know.
