The tough thing with okafor is we'd need a rim defender that can also shoot 3's. Who exists in the league like that?
Yeah... you're describing why Karl Towns might eventually dominate the NBA.
I do think part of the reason a player like Okafor is so polarizing is because some people are buying in harder to the "New NBA" thing than others.
Some people keep banging the "big men are dinosaurs!" drum suggesting that because of Golden State's success, small ball is the only way to go. Obviously, you can't really base the entire league on Golden State's success. And as we saw in Game 1 of the WCF where 6'10 Serge Ibaka, 7 foot Steven Adams and 6'11 Enes Kanter had their way with the smaller Warriors, there's still a possibility for a more conventional big man to have an impact in this league. It's less so the league going small... more so a lack of dominant bigs.
Okafor is the kind of guy that can tear up a defense. Just watch this clip of him putting in work against Dallas (and a pretty good defender in Zaza Pachulia):

https://www.youtube.com/watch?v=v5HAT4rEmxYHe can do it in a number of ways. And while parts of his game obviously need work, he's 20 freakin years old... he has time to work on them. It would be interesting to see how he played on a real NBA team that was trying to win. It was clear from the moment he was drafted that he was only in Philly to be an "asset"... and he seemed to wear that fact physically on him in every game he played. It's important to remember he's just a year removed from contributing to a national champion and was widely regarded as one of the top prospects in the world. His stint in Philly was far from embarrassing. Anthony Davis averaged 13.5 points, 8.2 rebounds and 1.8 blocks as a rookie. In a bubble, a 7 foot rookie putting up averages of 17.5 points, 7 rebounds, 1.2 blocks with 51% shooting is pretty darn encouraging. He's got some baggage, but it's overblown. The idea that the league is on the verge of having point guards play the center position is also overblown.
So you have people who want nothing to do with Okafor and think offering the #3 pick is a terrible idea. You have people who are super high on this draft and legitimately think a guy like Dunn will be better than Okafor. And then you have people like the Suns fans I mentioned earlier who would not only trade the #4 pick for Okafor, but also include a 24 year old PG (Brandon Knight) coming off a season averaging 20 points, 5 assists, 4 rebounds and 1.2 steals.
Here's hoping the actual Suns aren't as generous as those fans... because I'd be super excited for Ainge to land Okafor for just the #3 pick.
