"When Michael Jordan needed to get stronger, faster, and fitter, he turned to Tim Grover and the Attack Athletics training philosophy." Now, that philosophy—and the West Side facility—could be facing foreclosure. Attack Athletics stopped making mortgage payments back in February, and the bank is suing to collect the $8 million loan on the North Lawndale property. The 56,000-square-foot facility has 4 NBA regulation basketball courts, and it has served as training ground for Dwayne Wade and Gilbert Arenas. Out-of-work NBAer Michael Finley (pictured) is a client of Tim Grover, and he's named in the suit because he personally guaranteed $2 million of the loan.
