I feel like this is probably redundant at this point, but I will add my $.02 anyway.
What I like about Hill is that he is a veteran that can play defense, score and most importantly facilitate. He can play point forward, allowing Eddie to play off the ball w/o giving up size by having another 6'0 on the court.
I think this is truly an underrated upside. If he can play point forward we can carry an extra roster spot for another big or an athletic defensive stopper at the wing.
I think it would be best to do this to start the season and then try to use TA/Scal or a mid-season buyout to fill the pg need if it arises. I'd rather this than Pruitt, Lue or Marbury taking up a roster spot.
What I do not like about Grant Hill is that he is ancient and injury prone and he is backing up two guys that have a TON of mileage on them and have been ailing the past two seasons.
It would be optimal to add some depth behind Hill like a Warrick, Q Ross, or Matt Barnes (ie young, talented and athletic). But these guys are probably looking for more than the LLE and a 4th wing spot. So I fear we may be stuck with hoping that one of the Giddens/Walker/Allen group figure out how not to be liabilities.
