Perhaps you can say that the key to the season is Gallo, but you also have to say that this season is a key one for Gallinari.
By the end of this season I expect to see a pretty closee version of the kind of player Gallo is going to be for the rest of his career. This doesn't mean that he won't improve as he ages and gains experience, but for me he has to show significant improvement over last year.
I don't know how much importance we should give to his pre-season performance, but other than being more aggressive on the defensive boards, he did not show me anything new. His shot will come around, unless there is an injury limiting what he can do, but he has to show a more refined post-up game, more movement without the ball, and greater efficiency going to the basket this year- none of which was evident during pre-season.
I think he could carve out a career as the kind of player he has been so far, but I expect more than just jump shooting from him and will be disappointed if he continues to play as he did in the pre-season.
