I think the Suns chances of taking both games are very slim. The way I see it, the Spurs are a very well disciplined team, they rarely get rattled and in my viewing experience, they are rarely get down by more than ten points. From an outsider point of view, you guys have a ton of clutch guys, I cringe when even Horry or Berry have the ball near the three point line, not to mention any of the stars of the team.
For the Suns, Barbosa will be hot 80% of the time, Bell = less so, and Diaw hasn't done squat most of the year, but we all know he has some talent.
Fouls will kill the Suns and Pop knows this, I am sure he will adjust and attack with Duncan, Parker, and Ginobili.
