I don't think Thabeet will ever be a force on the offensive end however he could be one of the leagues best shot blocker and at 7'2" he could be a great rebounder. He will be a game changer on the defensive end and he will have a chance to be an excellent rebounder. In his prime he could put up 12 ppg, 12 rpg and 3 bpg. If he doesn't realize his potential he'll atleast be a 7 ppg, 6 rpg, 2 bpg valuable player. I compare him to Dikembe Mutombo
Hibbert is very fundamentally sound having already spent 3 years at college and a 7'2" player who spends 4 years at college and plays as a back to basket center can be a very dangerous weapon in todays NBA. In his prime I could see 20 ppg, 10 rpg and 3 apg and he is a safe bet to average 10, 10 and 2. I can't compare Hibbert to anyone.
Nicolas Batum is a very long player who appears to be a legit 6'8" and a swingman. He has a good shooting touching considering he is raw and has poor form on his shot. He is also very quick for 6'8" has a great wingspan and he can jump out of the gym. He should be a solid rebounder and he has point forward skills. If he goes to the SF/PF position in his prime he will average around 23 ppg, 10 rpg, 6 apg but if he stays at the SG/SF position in his prime he will average closer to 25 ppg, 7 rpg and 7 apg. He measured 6'7.75" with a 7'1" wingspan and also could still be growing and might end up around 6'9". I compare him to a Lamar Odom
or maybe a taller Tracy McGrady.
