Shannon Sharpe says if he were Chris Rock, he would've thrown haymakers on-stage at the Oscars ... with the NFL star explaining he would've tried to beat the hell out of Will Smith for slapping him.
Sharpe made the claim while breaking down the Academy Awards on FSI's "Undisputed" on Monday ... saying without hesitation, "I would have come up out of that tux. I would have whooped Will Smith's ass."
The 53-year-old Hall of Famer said he would not have been able to remain as calm as Rock .
