Golden State Warriors posed the question on their Facebook page of what undrafted FA's the fans would like to see in training camp. A lot of fans said Burrell and were impressed.
Found this blurb in a japanese paper this morning:
Power forward Justin Burrell, playing for the Golden State Warriors in the Summer League after leading Yokohama to the Final Four as an expansion team and earning 2011-12 regular-season MVP accolades, is attracting attention.
"Justin Burrell is impressing many NBA scouts," a bj-league source said. "I spoke with a scout for one NBA playoff team who really likes him, and has him on their team's short list of guys to bring in to camp, in case Golden State chooses not to."
