It always amazes me to see people give most of the credit to the OL for him being untouched, but it surely has more to do with his quick release. Last week, Ingram and Bosa were shutout, and Bosa was mic'd up talking about all his wins against LT Brown amounting to nothing. This week the top sack team in the NFL shutout. He goes against Aaron Donald in the Super Bowl. Is it his great OL? They deserve credit, so does their coach, but ... throughout the Patriots history, they've made do with castoffs, mid round draftees and mostly UDFAs. This team is no different. That starting 5 had a castoff from San Fran at LT, 3 mid round picks in Mason, Thuney and Cannon, and a UDFA in Andrews. Only Mason is a star OL out of all their guys. The fact he doesn't get sacked has a lot to do with his quick release, and his ability to move in the pocket, and his ability to read the defense pre-snap and post-snap. Most of the credit goes to Brady. He'd do the same with any other OL on any other team. That being said, when he's prevented from using the short passing system, teams can get pressure and hit him hard when he holds the ball longer looking downfield. The Eagles did it last year, and he responded well. The Giants did it well in the first SB and he responded not so well. In the second Giants SB, he was also hit but he had a very good game despite that. The flip side of this is Mahomes. The guy has all the ability in the world, but he held the ball way too long looking for a homerun and one of the most anemic DLs in the entire NFL sacked him multiple times.
OL play and DL play seems to be more of a matter of gameplan and system than anything else. Mahomes can transform his game and be even more dominant than he was this year if he isn't constantly looking for a homerun play.
