Pau Gasol, the 7 foot Spanish superstar small forward has caught Bulls GM Jerry Krause's attention.  The problem is that Gasol is thousands of miles away competing for F.C. Barcelona in the ACB playoffs in Spain.  "We know Pau very well," Krause said. "I've seen a lot of tape on him."  As Roman Modrowski of the Chicago Sun-Times reports, Krause is usually very strict about making draft prospects work out for his training staff, and despite the potential logistical problem, he hasn't given up on working out Gasol at the Berto Center.  In 1999 he worked Lamar Odom out on the eve of the draft, but what will Krause do is Gasol is not available?  "There won't be any time for a workout," said Gasol's Chicago-based agent, Herb Rudoy, who also represents Toni Kukoc. "I don't see any possible way he could make it over here in time after a rigorous season."
