If the Spurs play Spurs basketball, they will win in 5.
If the Spurs play discombobulated ball, it can easily go 6 or 7. Sean Elliot's analysis has been spot on. There isn't any ball movement to make the defense work and the Spurs are not getting easy buckets anymore. It's been one pass for a three point shot. If that's the case, the Lakers have two bigs + Artest that can gobble up rebounds. Also watch the phantom foul calls in favor of one of Stern's pet teams.
Let's hope that the Spurs pull it together.
