Now I didn't get everyone in this, but I think I included enough names that people recognize to make my point. Which is by the way, that there really aren't that many giant PF's out there anymore. Toward the end I included some centers just for the fun of it. People are worried about Griffin being only 6'9 or 6'8 inches, and therefore being too small to be sucessful in the league. Well judging by this list, if he's in the 6'8 to 6'8.50" range, he's right up there with the rest of the giants.
If you look at the list closely, you'll notice that the most sucessful rebounders are the one's with the tallest standing reach. Al Jefferson is only 6'8.50" tall, but has a 9'2" standing reach. How many people were surprised to find out that Stoudemire is only 6'8.50" tall. Theo Ratliff played center at 6'8.75", and was one of the leagues top shot blockers at one time. My point is, that if you can play, you can play. And no one can predict for sure how any player will turn out. Will anyone be stunned, that if at the pre-draft camp Thabeet measures out at 7'1.50" instead of 7'3", and will it matter? No, it won't! Because he's still a skilled shotblocker, even if he's an inch and a half shorter.
I could do this same equation for the shooting guards. Lets just say that if Harden is a legit 6'5", he's as tall as some of the NBA players that are playing SF. John Salmons is a little over 6'5". The great Bonzi was 6'5". Jim Jackson was a little over 6'5". Don't get caught up totaly in this height thing. Its not a bad thing to have it, but its not the be all, end all. Beno is one of the taller Pt guards in the NBA without shoes. So far, it hasn't made much of a difference. Chris Paul is under 6'. Not a fair comparison, I know. But why is that? Because one of them is very talented, and height has nothing to do with it.
