I'm not set on Shaq putting up a big game to save the day. As we saw in Game 6, Shaq is too banged up to put enough points on the boards in order to beat the Pistons. That means Dwayne Wade will have to put up a big game in the face of injury in order to get to the Finals. And he might have to put up at least 30.
On Inside the NBA the E.J., Kenny, and Charles were saying this is the perfect opportunity for role players to step up and make things happen for their team. But the only one that might have some success against this Detroit defense is Eddie Jones, and I don't think he'll have enough to make a difference in tonight's game.
Miami's main hope is that Detroit has the same offensive hiccups they had in Game 5, and that they are able to get some kind of production from the bench. Wade will play in this game, but I don't know if he can have the kind of impact needed to place his team over the top. The one good thing going for the Heat is that they are at home, where they should have a rabid Miami crowd that will be able to keep them motivated and intense. Hopefully the home factor will help them keep this close.
If I were the Spurs, I would want Miami to win. They are wounded and fatigued right now, and could easily be swept by a team that will have over a week off by the time Game 1 of the Finals tips off.
