hmmm well let's see.
Who is their compe ion and did they improve?
Suns: No. Lost Kurt Thomas who was their only Duncan defender. Picked up Grant Hill, who is more of a scorer than a defender. They don't need more scoring, there's only one ball. Picked up nothing of consequence in the draft.
Mavs: No. They've made essentially no changes. And they are now scarred from their first-round playoff loss last season.
How about the Spurs. Have they improved?
I think yes, a bit. Ime Udoka may be Bowen's backup. Other than that, they bring back their championship team.
Therefore, we conclude:
Their chances of winning this year are actually a bit better than last year. So I'd give them a 50-50 shot. If they are healthy going into the playoffs, I'd give them maybe a 60-40 chance.
