A lot has changed for the Idaho Stampede. New coach. New players. (That guy dunking in the photo? Long gone.) How about new attitude? Um, we shall see. Boise’s D-League hoopsters have started the season at 0-4 after a tough road swing, but the home opener is this weekend. First-year coach Mike Peck is hoping to tap the experience of former NBA player Coby Karl, plus exploit the raw talent of Michigan State product Durrell Summers, who led the team in scoring in each of the first four games.
