My picks are
Most surprising - Brandon Jennings, I knew he was good but didn't or never expect he could score (Especially in rookie season) 55 in 1 game, that's just amazing....
Most disappointing - Hasheem Thabeet, well no need to explain why, 1 PPG 1.9 RPG and only 0.9 Blocks for a 7'3'' guy? Seems like a 2nd round rookie for me than a 2nd draft pick.
