Intriguing teams as a defensive-minded center, Ty Walker has met with the Oklahoma City Thunder, Golden State Warriors and Philadelphia 76ers during this month’s NBA D-League Showcase, league sources told RealGM.

At 7-feet, Walker is averaging 8.3 rebounds and 3.7 blocks per game with the Maine Red Claws, recording a D-League season-high of eight blocks earlier in the season. His wingspan (7-foot-6) and standing reach (9-foot-5) have left similarities to to JaVale McGee and Hasheem Thabeet, respectively, on the defensive end, and he helped hold Malcolm Thomas to just nine points on four of 13 shooting in Tuesday’s game against the Austin Toros.

Walker had also received interest as a potential training camp invitation in September.

For the season, Walker is averaging seven points in 27.5 minutes. The 24-year-old went undrafted in 2012 after four years at Wake Forest.
