Leaders are born, you can tell a leader as soon as you meet some one...I read books on body language, did a little research own my own, and you really would be surprise by how much you can figure a person out by there body movement, in just minutes, even seconds if you can see them walking.
I think gallo will be a very good player once he gets that confidence, he needs to get some games under his belt, and what I mean By games, he actually needs to win some games on his own, carry us for a stretch. He'll never be a leader, but I do see him being able to be 2nd option on a very good team.
I think leaders come out of the gate like, Kevin durant, brandon roy, d will J Kidd shawn Kemp ect...Pipin could never be looked at as a leader, and he had the skills and work ethic, but you saw how he responed when MJ stepped aside for a minute. That how i feel about gallo, he could be as good as PIP, but to lead a team for 82 games, i just don't see it..
