National TV exposure comes a little earlier than expected this week for Lefty Driesell, the Maryland coach whose grudge against the game's three-point shot has gotten him into a shootout with CBS Sports analyst Billy Packer.

CBS is taping the shootout--20 shots each from outside the three-point arc at Cole Field House, public invited--at noon Wednesday, and plans to show it during the network's Big Eight coverage Sunday. "If I lose, I'm donating $2,500 to the Basketball Hall of Fame," said Packer, a vocal proponent of the three-point shot, "so I hope Lefty realizes that I'm taking this as a serious challenge."

Driesell made the challenge by phone as Packer sat courtside at a CBS telecast last month. After a taped feature, in which Driesell demonstrated his mistrust of the three-pointer by making two, a jump shot and a hook shot, Packer said he doubted Driesell made them on the first try.

Driesell, reportedly working out and dieting the last two weeks in preparation for the TV exposure that playoffs bring ("So I can fit into my vest"), claims he did. Film at 11 . . .
