Draft Watch: The return of the sky Walker

CHICAGO -- The city was abuzz Wednesday morning, fresh off the news that the Bulls had done the impossible -- winning the draft lottery despite having just a 1.7 percent chance.

As the city debated whom the Bulls should take with the No. 1 pick -- Michael Beasley or Derrick Rose, I spent the day watching draft prospects in Tim Grover's new state-of-the-art training facility -- the A.T.T.A.C.K. Athletics Center.

Grover's new gym is so cutting-edge it puts even the best NBA training facilities to shame. Four full NBA courts, spacious locker rooms, incredible workout machines, including an underwater treadmill, plus a players' lounge with an 85-inch plasma screen, pool tables, and private rooms for sleeping and playing video games -- it's amazing.

In the dressing room are lockers for Michael Jordan, Kobe Bryant and Dwyane Wade -- three of Grover's most famous professional clients -- along with individual stalls with gold-plated names for his pre-draft clients: O.J. Mayo, Bill Walker, Brandon Rush, Chris Douglas-Roberts, Donte Greene and others.

Grover's gym has become such a destination that William "Worldwide" Wesley sat at courtside the entire day. He seemed perfectly at home.

I've been coming to Grover's pre-draft workouts since 2001. No one has a better reputation for getting players stronger and more explosive and for teaching core pro fundamentals that will be crucial to NBA success.

On Friday, we'll do a full feature and breakdown of Grover's top client: Mayo. Here's a look at some of the other top prospects in the gym, starting with Mayo's high school teammate Walker.
