But some of the players Arenas has been running with at Attack Athletics -- formed by Grover, who famously trained Michael Jordan -- have been more effusive in their praise. It has been an unofficial All-Star week in Chicago, with stars, former stars and future stars -- Arenas, LeBron James, Chicago native Dwyane Wade and O.J. Mayo, to name a few -- running the floor at Grover's place. But Arenas, one of the NBA's best showmen, has left the news-breaking to others.

"Runs at attack were pretty good today," Andre Iguodala wrote on Twitter. "gilbert arenas is back like he left his black card!"

"he aint lyin yall!!" Quentin Richardson replied. "Thats real!"
