Gallo is my favorite - he's got the skills and he's got the mentality to succeed. All he needs is the experience.
Chandler/Lee are tied for a close second. Consistently bring it every night.
Douglas is quickly closing the gap between him and the trio as well.

I really hope to see all four with the team for a long time.

I would say Gallo then douglas then lee. Gallo has to work on his dunk finish hahahah
