I don't think Marbury has scared us away. It's summer, he's just having fun. He can also be serious at times, as shown in the stream. We know who he is and what he brings. The minimum offer will still be on the table; it's up to him.
But in case he won't re-join us, Williams could be a very interesting option. Come on. Rondo's going to play close to 40 a night, and how many games has he missed the last two years? 7? Big deal! If he gets hurt, Williams should do fine in those couple of games.
And by the way, Williams is washed up and injury-prone? What? Maybe he has some injury problems, but we took a chance on Miles last season, who hadn't played in 2 years. J-Will just quit for family reasons. He was physically able to play.
So if Marbury doesn't re-sign, it's a no-brainer to sign him.
