Good point. Without an offensive line, the offense will go nowhere. Look what happened to Mahomes a few years back in the Super Bowl when his Oline was decimated. He was running for life all night long and the KC offense looked bad. They had the QB, TE, and receivers, but a poor Oline. Norm Chow once said in a radio interview, 80% of a successful passing game comes from a good offensive line. The same could be said for the running game.
