I think Chandler is doing fine... if anything I think Fields and Jefferies are playing extremely well but they have both been very active on the offensive side, once Melo fully gets back in the mix I want to see both Fields and Jefferies be even more selective with their shots... but geeze Lin has been making Jefferies look like he has some sort of offense lol.
And this is the regular season and the time to get out your frustrations... better now Chandler get a few technicals then during the playoffs. I think Chandler getting frustrated is actually positive in the long run for the team, it shows how much he wants to win and has his heart in the games.
