A gapping whole in the SFposition for the Nets

With the departure of a star, like RJ, who has done nothing but good for the Nets, there are always going to be some negatives. One of them is that there is a huge whole where he used to be. A whole that one man can't fill, unless he is a star.
Who will play the 3 in the starting lineup?
Boki Nachabar- He came to New Jersey and stepped up his game but not exactly enough to be propelled into the starting lineup. He averaged 9.8 points 3.5 rebounds, and 1.2points of the bench last year. He is probably going to be considered most here, and will win the starting job, at the beginning of the season, assuming he will be re-signed.
Chris Douglas Roberts- CDR will have to impress to get a spot in the starting lineup. And if he does reach the starting line up he will most likely do it in the middle of the season, buy he will get playing time, because there really is no one else.
Mo Ager- He really doesn't have a chance to get the starting spot, he will have to worry about making the roster first.
Yi Jianlian- Yi will be in the starting line up for sure, it depends were though. He could play either the 3 4 or 5 positions. He probably wont start at the 3, but he will see game time there if the Nets go big, which the Nets might be able to do for the first time, in along time.
A Free agent could also come in and start, it could be someone like JR Smith, or Mikael Peitrus.
Everyone else is going to have to step in when their name is called, because they will get thir chance.
