It's coming up here is some news.
"The Wolves have signed Toure Murry and John Lucas III to bring them to camp and give both guards a shot at a roster spot, league sources say"

Neither of those guys are going to wow anyone but both have NBA experience and Lucas has played for Thibs. If a roster spot opens up one way or another either guy would be ok as a non guaranteed player that can be replaced if something better comes along. Murry is interesting because he can probably play 1-3.
