Whiteside chronicled his hangout with the pass catcher on his infamous Snapchat feed. First he showed Brown sinking several 3-pointers, with the caption: "AB for 3."
He later posted up the Steelers star and drained some downtown jumpers with ease. Brown had no chance at guarding the Heat's superstar, who toyed with the smaller stud athlete.
"Cardio work with big bro @hassanwhiteside #wethebest #boomin#DefeatTheOdds," Brown wrote on an Instagram post.
"Agent Block" is listed at 7-feet, while Brown comes in at 5-foot, 10-inches. Brown grew up in Miami before starring at Central Michigan and eventually in the NFL. He is a 3-time All-Pro and has led the league in receptions in two of the last three seasons.
Last offseason Whiteside signed a four-year, $98 million contract to return to the Heat. Brown signed a four-year, $68 million contract extension in February with the Steelers.
Whiteside, 27, led the NBA in rebounds this season and in blocks in 2015. Brown has spent most of his offseason working out in his hometown, including his one-on-one battles with former Cincinnati Bengals wide receiver Chad Johnson.
