'Nique was an exciting scorer, but that's about all he did and it's not like he did it at great efficiency. He was basically the previous generation's Carmelo Anthony. Drexler wasn't a volume scorer like 'Nique, but he was a bit more efficient, a far better play-maker and a better defender.
Would you rather have a prime, healthy Grant Hill or a prime, healthy Carmelo? I'd take Hill every time and, to me, that's equivalent to Drexler over Wilkins.
