These numbers may be skewed because of the two blowouts, but here's the split for San Antonio's Big Three (Parker, Ginobili, Duncan) in wins vs. losses for the series. I also looked up the team's total assists and FG%.
Wins:
Parker 25-45, 56%, 23 ppg, 15 attempts/game
Ginobili 24-44, 55%, 23 ppg, 15 attempts/game
Duncan 16-28, 57%, 16 ppg, 9 attempts/game
Team: 27 apg, 55% FG
Losses:
Parker 14-33, 42%, 17 ppg, 16.5 attempts/game
Ginobili 4-13, 31%, 6 ppg, 6.5 attempts/game
Duncan 19-31, 61%, 23 ppg, 16 attempts/game
Team: 16 apg, 46% FG
Looks like Manu Ginobili is the X-factor. If we can keep him from getting good looks at the basket and keep him from driving the rim, we can win Game 6. Tony Parker is just as aggressive in losses as he is in wins, but he's having trouble in Arco. Keep Kevin Martin chasing him around and tiring him out. We need to trap both of these guys off the picks and make them throw some soft passes.
Tim Duncan hasn't been stellar in losses or wins, but we can deal with a dominant performance from him; we can't deal with a dominant performance from the other two. And if Bonzi can't keep Bruce F. Bowen from going 7-9, then that presents another problem.
This game is completely winable. Bonzi is dependable for a solid performance. Ron is going to show up, but he needs to score in the flow of the game, not force the action. (By the way, who else thinks it odd that our two best low-post players are swingmen?) Kevin needs to be solid off the bench. I think we can book those three, because they've been pretty consistent so far.
Mike Bibby, Brad Miller and Shareef Abdur-Rahim have got to step up and play hard offensively and defensively. Mike needs to shoot well and make the defense pay for collapsing on Bonzi and Ron. We can do without Brad's offense - as we saw in Games 2 and 3 - but if he plays like he's 6'2" on defense and on the glass, we can't win. If I'm not mistaken, Mike is averaging more rebounds than Brad. I'd rather see him get after it hard and foul out than see him play like a WNBA point guard. I'm not asking for an All-Star performance, but we need 13 and 8 with a few altered shots from our starting center. SAR has to be aggressive offensively and get Tim Duncan in foul trouble, just like in Game 2. He has to attack on offense and stay big on the boards. Kenny Thomas just needs to give us 25 minutes of solid defense and hit a couple of shots.
To simplify, if we can keep Ginobili and Parker out of the lane and make shots down the stretch, we can win.
