My point was more about the x's and o's of how on paper it was supposed to be. More in practice, film study, etc....then in games.
Another PG with time in the system would give Marshall a sense of how we want him to run the offense in theory, because everyone else could point it out during the intra-team activities. In games, Dragic does go 'rouge' though and sometimes plays more like a score first pg. I agree he can get totally wild. Though sometimes that does work out.
I do agree with the idea that Marshall might already know what we want. So perhaps it is a moot point to bring in anyone. Marshall might at his core play more to the Suns philosophy naturally than any of the others after coaching. He has some major flaws that could completely limit his ceiling. But his strengths are ones that seem tailor made for our style.
I guess my point is just to have another guy around to make sure that's the case outside of game time and to ease the transition. But I'd be just fine with not having Dragic as well. We have other needs, and having two PG's, and rights to Brooks, means we have cheaper options already in the fold.
