"Gallinari Mason and yes Mosgov haven't been holding their weight. For this team to be good--we need to get more out of those 36 minutes."
Mosgov has a number of important attributes. He is a 7'1" player that can run, shoot, pass and block shots. If you watch the games you can see him calling for the ball, but rarely getting it. He also has a great deal of trouble figuring out what fouls the referees will call, and what things he can get away with. Mosgov has huge upside, and is most definitely worth educating about how to best play in the NBA. We need to continue giving him significant minutes so he can turn himself into a valuable NBA big man for the Knicks.
Gallinari is shooting badly as a result of his bad wrist. Unfortunately he cannot perform the volume of practice shooting that he has been accustomed to daily. Why would you make a decision about Gallinari future contributions without giving him a chance first to get healthier?
Knicks have decided Walker is the other shooting guard to get playing time, along with Toney Douglas, and Landry Fields. Mason seems to me to be a reserve going forward, so I don't think he will be providing any of those 36 minutes of bad basketball.
What have I misunderstood?
