Shawn Oakman is wasting no time proving he's serious about the NFL ... putting in some serious work in the gym just days after proclaiming his dream of playing in the league.
Oakman was found NOT GUILTY in his rape case last month ... and has since vowed to work his ass off and show teams he deserves a shot to play in the NFL.
Of course, Oakman was a projected 1st-round draft pick while playing at Baylor, but went untouched in the 2016 NFL Draft after he was arrested and charged with raping a woman at his apartment.
