I'm trying to win a little bet: My friend has a poster he claims is from the '80s. It's a picture of a Sonics player (African-American) wearing a jersey with #51 on it. He's stading on the path around Green Lake in Seattle with roller skates on, holding a basketball. The caption on the poster says ' "Skate" King '. He says it was a promotional poster given out at the game, but he couldn't figure out who the player was. I bet that I could get a name! Anyone with any ideas? Someone have an NBA encyclopedia with old team rosters? Thanks in advance!
