I'd take Shaq, right now. Oh, it would be great to have the younger Shaq. It would be great to have a lot of things. But Shaq, as he is right now, is not only a dominant post threat, but one of only two truly dominant post threats in the league. Not to mention, the team that got better play from its CENTER in the finals has won the championship across the last 25 years - more times than any other position. Even if the difference is the difference between Luc Longely and Greg Ostertag. With Shaq, that advantage is almost automatically mine.
And if Shaq isn't of sufficient value next year, there's always someone willing to take him off my hands.
I like Wade a lot better, but if the name of the game is winning the championship, I'll take Shaq.
