How Patriots are combating illegal formation penalties in practice originally appeared on NBC Sports Boston
NFL referees made an emphasis during the preseason to call illegal formation penalties on offensive linemen, and many teams, including the New England Patriots, were flagged a bunch of times as a result.
Well, that emphasis didn't decrease during Thursday's regular season opener between the Baltimore Ravens and Kansas City Chiefs at Arrowhead Stadium.
The Ravens offensive line was penalized for an illegal formation three times on their first drive of the game.
