Kareem Rush..Royal Ivey - Additions or Replacements???

After the sixers signed royal ivey..It was like..Ok..he's a lock down defender, he's a better three point shooter than anybody we have on the roster, and his personality brings more heat of the bench. However, the sixers just signed kareem rush(39% 3 point shooter) who is definately somebody we needed..but are these signings made to add depth and shooting to our roster..or are they early signings made for when they lose andre or lou...or both??? I can only hope not..but all i know is that we only had a little bit of spending money left and unless we plan on getting rid of Willie Green like i hoped..teams will now have the ability to give offers that we simply cant match
