On the subject of McHale, he was not this unreal, superstar player... that player was Bird.
What McHale was was a prodigy on the block as far as getting his shot off, with confounding post moves, when he caught the ball on a pass. Otherwise, he was a normal, hard working, above average player. This is analogous to that student who knew 12 languages (a brainiac in that aspect) but essentially got B+'s to A's in everything else by doing all the work, like any other hard working student. But average in those dozen languages and he looks like a all-round genius. That's McHale.
His defense was assisted by his lengthy arms and his rebounding abilities was below that of Bird, Chief, or even Maxwell. All and all, he contributes as much as a Stoudamire, a periodic great showing, but otherwise, just another above average, hard working big man down low.
Whereas the Bird to Nowitzki comparisons are completely invalid. Nowitzki is the rich man's version of Raef LaFrentz. And judging by Raef's bloated salary, its probably a stupid person in the upper middle class than a rich one. The only player close to Bird today is Pierce.
