There is more than just Whitey's source too -- there was some indication that Joerger and Conley might be at odds. Or Conley vs. the system. If it was the latter, then Joerger reportedly had some issue with the system too, so he might be able to tell Conley they were going to run something more Conley-friendly. But if it was the former, Joerger's presence might actually eliminate the chances of signing Conley rather than increase them.
On the other hand rumors are the Memphis roleplayers like Barnes and Lee may be in play for us, so we got the important guys anyway.
