J.R. Smith Is 'Donkey of the Day,' Says Charlamagne tha God

"J.R. Smith ran away from that basket the way Pusha T claims Drake ran away from his responsibilities as a father."

That's why Charlamagne tha God awarded Smith his "Donkey of the Day" title on "The Breakfast Club" Friday morning ... blasting the Cavs player blunder that cost LeBron Game 1 of the NBA Finals.

"I don't know if J.R. Smith uses drugs," Char said ... "but if he does, I think it's his duty as an American citizen to tell us what the hell he's on or has been on so we don't make the same mistakes."

Charlamagne also blasted Smith for his explanation of the blunder ... saying Smith clearly did NOT know the game was tied.
