Dwight Howard has resorted to old football tactics in order to hold on to the basketball, per the AJC:
As Howard was about to check back into the game, he sprayed his hands at the scorer’s table with a can covered in white tape – apparently to hide its contents. He entered the game as Paul Millsap was at the free-throw line and grabbed the ball after a made attempt. When Millsap got the ball back it clearly had a foreign substance on it.
Official Monty McCutchen grabbed the ball and went to each bench to issue a warning, saying ‘Stickum is illegal in the NBA.’ After first going to the Hawks bench he made his way toward the Rockets bench. Rockets coach J.B. Bickerstaff slid in front of the can, still at the scorer’s table. McCutchen noted he knew what Bickerstaff was hiding.
