Tua made a lot of very high degree of difficulty throws against the Chargers. They got pressure on him. The DBs gave decent coverage. This is like a college basketball team that shoots 65% in a game, and everyone thinks they're fantastic. The opposing team played solid defense, but everything went in that night. They can't do it again the next game because it's almost impossible.
As for Tyreek's first game last year, remember they sent him out of the backfield and in the slot, and rarely sent him downfield. He gained all his yards that way. They exploited us the way the Bills did with McKenzie the prior year. But things have changed on the Patriot defense. It's not Bentley, Bryant and McCourty with those short responsibilities anymore.
