I think it will be interesting to say the least. I think Hanford will be tough again this year with Tommy Begalka and the supporting cast. No big guys like Severin, which should open (speed) up their game.
On the others, Southridge (with Jason Munns)and Kennewick (with Robbie Mitchell) will be tough. Kamiakin has a new coach from River Ridge with roots in the Tri-Cities, but I am not sure he can turn the program around in the first season. Eastmont, West Valley, and Sunnyside -- I'm not to sure of their talent base, but based on last season's teams and JV teams -- I don't remember anything that special.
It will be fun to watch though...
