In 1950, players from the AAFC's defunct teams – including the Bills – went into a dispersal draft. Gibron, however, was sold along with halfback Rex Bumgardner and defensive tackle John Kissell to the Browns in a deal that gave Bills owner James Breuil a 25% share in the team. In the Browns, Gibron joined a team that had won all of the AAFC's four championships behind an offense that featured quarterback Otto Graham, fullback Marion Motley and ends Mac Speedie and Dante Lavelli. Yet while the Browns had been the league's best team, many sportswriters and owners doubted that the team would continue its string of success against NFL teams starting in 1950. Cleveland started the season by beating the previous year's NFL champion Philadelphia Eagles and went on to win the NFL championship over the Los Angeles Rams.
