"Billups and Rip had 5 fouls each"
Rip is pretty prolific fouler. I've seen end games with 5, or foul out, several times this season, head-band tossing, including getting ejected for double Ts. So last night was nothing special for him.
I think the Pistons, backs to the wall, took their best shot last night, solid defense, hitting their shots, and they still needed a gawdaful horrible game from the Spurs to win it, at home. Had Manu and Tim been giving their avg playoff game (which the Pistons had a hand in), it would be 3-0.
I'm fairly sure it will go 6 games, with Spurs coming home 3-2 to finish it.
