I don't think he is playing his game and he is drowning a bit due to trying to adjust to the center role and also how bad of a season we are having as a team. His energy has decreased from the beginning of the year and I don't blame the kid.
You may be right but the drowning may have more to do with expectations and the contract he signed. I remember when I first turned on Desharnais and it was very shortly after he signed his new deal and stopped playing like he had to just to make it here.
What we do know about his time in Tampa is he had to earn his ice time with that club. Some players don't react well to being gifted opportunity and often team mates don't react well to players who either aren't or don't seem to be giving much effort.
