OKC had the best backup PG in the league before Maynor was lost for the season In January. Scott Brooks really relied on his backup PG to play quality minutes, so the high energy Westbrook could be fresh. Rookie Reggie Jackson was shaky at the point and Royal Ivey just isn't very good.
Fisher, despite his declining everything, is a great pick up. He will stabilize their second unit, and will be out there with two very good outside shooters, in Harden and Cook, so that unit should be able to put some points up. Harden can initiate a lot of offense in the half court, which works perfectly for Fisher.
I really hope the Thunder get another shot at the Lakers in the playoffs.
