Not a bad signing. He's not some old vet that will be compelled to get minutes (like Howard) or a guy who's been on the team forever and gets minutes because "he knows the system" ala CJ.
At the worst he doesn't pan out and it's a one year deal.
I'm guessing Murphy may get a 14th spot and play a lot of D League.
As of now (well if this is legit) the roster looks like:
PG: Mo, Watson, Tinsley
SG/SF: Hayward, Marvin, Burks, Foye,
C/PF: Al, Favors, Sap, Kanter, Evans
I'm guessing Murphy will get signed as there is space, though probably not make a lot of active rosters unless he's that good. I do wonder about Carroll now.
