swagger until the second half--it's the confidence that comes from getting in there and getting some license to do things his way. In the few NBA games where he was called into major action for whatever reason, he also showcased that same rhythm. It has just proved impossible for him to gather that type of confidence on such a short leash.
It should also be noted that the average height in the NBA is around 6'7". The average height of the Grand Rapids team is 6'5.5". Doesn't sound like much, but when you're a 6'2" professional basketball player, it actually is.
