There are a lot of different personalities on the team. Not everybody is going to express themselves in the same way. Naz never smiled on the court during his first summer because he was focused on playing defense and making life miserable for the guy he was guarding.
Early reports seem to indicate the overall chemistry of the team is already better than last year and the team is growing closer. It is good for a team to have different personalities during a long season to either amp up or release the pressure during a long year. Ejim was an intense personality that demanded the team to focus when they were getting lose, Niang was able to relax the locker room with humor. Both are all time Cyclones and were a great balance the two years they played.
I just came across the Daily recap of last night if anyone is interested. THT almost had a triple double on a night were he looked tired is impressive.
