I did some research on him. he played at New Mexico State and spent the past season in Turkey, which he claims is the most physical league int he world. He also claimed that he led the league in scoring, at 20 ppg.
Gibson claims to be a lot more physical player than he was in college, and a master at the pick/roll game. he had a 3.7/2.5 assist to TO ratio in Turkey, which he didn't mention in his interview.
He was so off the radar that Draft Express didn't even profile him with his draft class.
