Its basically the same team with small upgrades. More of a change was needed to last years roster than what the spurs have done to increase the probability to another le. Splitter and Anderson will not push this team to a championship level team.
But if everything works out just right like further improvements with Hill and Blair, Parker regaining form from a couple of years ago, Splitter and Anderson are better than expected, Manu plays like the 2nd half of last year, everyone stays healthy and the other top teams have injuries than the spurs can sneak in. But there are a lot of variables that have to fall just right for the spurs to go far. Not likely but not impossible.
