OK, wow. It would be nice to be able to actually discuss these comparisons without the need for extreme hyperbole. Anyhow, read through the first few pages and have a few things to add in.
First point is around height. I am not sure what advantage poster's are trying to gain from this regarding Wilt's competition to current. Wilt was both tall and long so he'd be just as freaky in today's game. If I were going to make an argument around size of competition I would start with the length of players versus the height.
Simply put, you are scouted much harder today and length has become just as or even more important then overall height. If I am not mistaken, Dwight's standing reach is only a few inches shorter than Wilt's, who would be noticably shorter standing back to back which is also part of the reason why Russell was so effective. Great athlete, long arms. However, the league then from all the film I watched and even shown in this thread wasn't filled with players per position who could play taller than their height.
Many players well under 7' have very impressive wingspans which allow them to compensate for any inches lost in total height. I don't believe it is fair to blame Wilt for this though, as this is the progression of the game after him and which arguably he started the trend, but if comparing the two, it is a definate factor to consider.
As for thread question on who I would choose. I've been watching a lot more film regarding Wilt but the more I watch, the more unsure I am with him playing in today's game. In Wilt's era, I'd choose him over Duncan during that period because the rules and how the game was played then was perfectly suited for Wilt. I would choose Duncan for today's game, pretty confidently.
The problem is, there isn't enough footage on him but from what I watched on Wilt highlight video's or the cut & pasted games I think today's length per position would really bother Wilt and limit his 2 way effectiveness. I view Wilt as this well ahead of his time athlete who truly was a unique specimen. Outstanding size & length providing 2 way impact. However, I just haven't seen enough, especially regular ol games, not just highlight or select playoff games to trust how effective he'd be over Duncan, especially given the teams Duncan has competited against.
I actually have developed an appreciation for Wilt and what he has done to the game but to me, it shouldn't cross into the current nba model. I've really thought long and hard about this and for me to be able to say Wilt would mean I'd have to bet on him basically being able to modify so much of what he did and play style back in the 60's etc. And because of that, much of what he gets praised for during his era, he wouldn't be able to execute today so I need to go with the proven competitor.
I think Wilt was an incredible shotblocker for his day, fantastic timing and we can see footage of this. You also see that he was a good rebounder, and what I liked is that he boxed out his opposing player to gain more of an advantage. Duncan was also a very good rebounder & shot blocker and did this in a league where he wasn't considered the best athlete and one where Wilt wouldn't be head and shoulders above the competition like he was.
If I am being honest here, Wilt's fingerroll to the basket move would be eaten alive today and he'd be stript an awful lot trying to execute in the post. He'd most likely develop his fadeaway jumper but he'd be in a world where almost all players play above the rim which just wasn't what he played in. Duncan is not an offensive anchor but he is capable of carrying a large portion of the scoring load and increasing this into the post season. His defense, rebounding is pretty elite and he has a very good basketball IQ. He had a great coach in Pops from the start, but his poise and execution are very high level.
I think Wilt and all his great accomplishments and records deserve recognition and praise but should be left in his own time. Too many what if's that I am not sold on when comparing to more modern day players, too little full game coverage (he wasn't a highlight in every play, neither was MJ) and just way too many differences in how the game was played.
I also think the Wilt supporter's should be open minded to the idea that he's been away from the game now for over 40 years and you can't stay on top forever. I mean, as the game continues to progress, I would hope newer and better players come along utilizing all this information of past greats to help make others better. One simply cannot assume that a pioneer would excel if given the same tools, especially when they already played at such a high level to begin with. Personally, 40 years from now, I hope the consenus top 10 list looks completely different, hell imagine MJ barely making top 10
