I'm not surprised. Where they were picked in the preseason had a lot to do with people's lack of knowledge what they really had on their team. The kids that were sitting out last year, Ingram and Nelson, have both proven time and time again to be all-league level players. That's a big part of their success. Reggie and his staff are good coaches.
The speed of the game is such a hard adjustment for any player. This is just so much faster than the JC or high school level. Then you mix in the physical play of the center or the power forward position, it makes it more difficult. Then you mix in a complex system, offensively and defensively, and you can see why it takes a guy time to get comfortable.
