I'm a little surprised that some of these names haven't been thrown about on GSOM recently. I personally see them as temporary cheap solutions to the current gaps in our roster assuming we don't come flying out of left field with a major roster move:
DJ Augustin - Personally think a swap for Dorrell fills needs on both teams just fine.
Kwame Brown - Wouldn't mind his defensive presence as a back-up. I really think Festus is athletic enough to play alongside Bogs and can actually play limited minutes as a backup 4, so signing a backup 5 for the defense wouldn't hurt .
Johnny Flynn - Cheap but..... all around ew
Javale Mcgee - Also one of those athletic 7'fters that I fully feel competant can keep up with 4's defensively
Anthony Tolliver - Loved him last time in a Dubs uni
This is just for the sake of conversation. The link is just a giant list of FA's.
