If we sign another point guard, they're not likely to be part of the rotation. They'll be one of those "break-glass-in-case-of-emergency" players, someone who can step in and play 35 minutes if Rondo twists his ankle. Someone who can bring the ball up the court and get the ball into the hands of Pierce/Ray/KG. Someone who's not going to be a huge negative on the court, as I'm worried Eddie might be if we asked him to play the point for 40 minutes.
That makes me leery of bringing aboard someone as old as Bobby Jackson; if we needed him to play 35 minutes a game for two or three weeks, could his body handle it? He might be OK as a 10- or 15-minute/night player, but that's not really what we need; we need someone who basically is going to be OK with racking up DNP-CDs all season long, but if there's an injury can play big minutes.
I don't know how anyone can advocate for Jason Williams after he's been out of the league for a year. He was on the decline even before he retired, and even in his prime couldn't play a lick of D. NY kicked the tires and declined to pursue him, despire the fact that their starting PG is Chris Freakin' Duhon. If the C's want to bring him in for a workout, fine, but I don't think ANY of us are in a position to really say "WHITE CHOCOLATE'S THE ANSWER!" when we haven't seen him on the court in ages.
Ty Lue... I don't care. I don't see how he would hurt, I like him better than Pruitt, but again - he won't see the court UNLESS Rondo gets hurt.
Best-case; trade for Dooling. Seems to make sense for both teams, save NJ some $$ as they retool, we get a guy who can play the point, play some D, and *would* likely be a member of the regular rotation. He's veteran but not ancient like Jackson. Give them either Tony and Giddens/Walker (pray that we keep the right one), or Tony and some cash to pay some of his salary.
If we could add Dooling - a proven, albeit limited - backup at the PG spot, we're pretty solid across the board on the bench. If it's a Tony + Giddens trade for Dooling, that would still leave one roster spot open; bring aboard a couple of fringe-NBA guys (Swift?) and let them battle it out with Hudson for that last spot on the roster.
