AT ONE POINT early in this NBA playoff series, when the Raptors were down two games to the Detroit Pistons ? and the temptation now is to wonder how ? Keon Clark had performed an extremely rare trick.

He was both 6 feet 11 inches tall and yet partly invisible. He's not a robust guy ? he might need to run around in the shower to get wet ? but, geez, where did he and all his potential free-agent riches go?

Wherever they went, they're back now. Clark was the proud possessor of an often thunderous 19 points and 16 rebounds, both playoff career highs, plus a critical fourth-quarter blocked shot on Corliss Williamson, in last night's 89-83 get-even session against the confused and confusing Pistons at the Air Canada Centre.
