Lin, I like because he looks to pass before shooting...his defense can use some improving but that comes with minutes.
Douglas, I also like but I don't see him as a full time PG under D'Ants system. He's more of a energy guy with great defensive abilities. His range has improved and I expect other parts of his game to do the same. He's a hard worker and is commited to learning. His passing is improving but D'ant confuses the poor dude with this hurry up and shoot the 3 point gameplay.
Shumpert, I think will do better than both TD and Lin, He understands Defense and knows the flow of offense comes when the energy/momentum is in his/our teams favour. Besides, he has some NY swag and that will go a long way in this city. Over the holidays, I listened to some of his unreleased album (rapp) and was surprised at how NYC he sounded, Cool dude too, btw. He knows the NBA is going to be his bread and butter, hopefully he dosen't get caught up in the inner city life...especially when he dosen't have to.
B. Davis, I don't know. I feel many people are just too optimistic and have no real idea just how bad of an injury Davis has. To think he will come back and automatically play well (or play at all) will be a set up for disappointment. With these kinds of injuries you have to be extremely careful, it's just a game of ball not the game of life. He'll have to decide what's more important if (or when) the injury is tweeked again. Besides, I'm not sure if he'll have the stamina/endurance, or durability to last in this fast pace system. Under any other coach... he'll probably be a great asset to the team. But, I don't expect the Davis of old to play, I do see his experience being a big plus, thou. how much? depends on the coach.
