The 6-5 guard played most recently for the Knicks in the Vegas Summer League averaging 4 points and 2.4 rebounds in just over 11 minutes per game.
Prior to that, he played for the Arkansas RimRockers of the NBDL, averaging 6.8 points and 2.7 rebounds per game.
I did the mandatory YouTube search for Famutimi like I do with most Spurs signings and I came up with a compilation of Dunks by Arkansas players. Famutimi is #23 in this video.
