DENVER -- Kelly Forbes has a pretty good save percentage. During the Stars' 6-4 loss to Colorado on Saturday night, the Stars video coach (along with head coach Jim Montgomery) helped negate two Avalanche goals with goaltender interference challenges. The correct challenges helped the Stars to the first intermission down 3-0 instead of 5-0.The first came on Colin Wilson's apparent goal at 8:30 of the first period, when he flung a shot on goal that clipped Anton Khudobin's stick and arched over his head into the net.
