Watch him around the basket. He is almost always the last to react and jump/move for a rebound. Remember the famous line from Scott Skiles about Eddy Curry and how he could be a better rebounder? Jump. This has nothing to do with him being out of shape. Some people have the instinct for rebounding, some don't.Rebounding, shot blocking, screening, good hands. You say he is “slow to react”, can you be more specific? Seems like a lot of people just want to hate on him because he is overweight and they are convinced he is lazy. I remember people complaining about Brad Lohaus and Les Jepsen being goofy and uncoordinated. It just takes big guys longer to develop.
