In 1972, when the Knicks selected Henry Bibby with the 58th pick, Canada was a refuge for draft dodgers, and a low draft-lottery number was undesirable. The times, they have a-changed. On Wednesday (TNT, 7:30 p.m.) dozens of young Americans will converge upon Vancouver for the NBA draft. The Clippers most likely will take Henry's son, Arizona point guard Mike, with the first pick (page 76). Meanwhile, fans can hope that owners and players contemplating a lockout will sing a chorus of "It's one, two, three/What are we fightin' for?"
