Because there are maybe 5 QBs in the NFL that can execute for 60 mins without a mistake. It’s just playing the odds. Sometimes they play great, mistake-free ball and you tip your cap to them. But most of the time the only sure-fire way to lose is giving them big chunks of yardage because you’re trying to throw all kinds of exotic blitzes at them.
And the Pats have given up more 20+ plays than anyone over the last few years. Their red zone defense has saved them in that regard.
Offensively it’s about taking what’s there. Taking risks by trying to force it results in turnovers and losses.
Line up, make sure everyone has the call, try to get pressure with three or four guys and most of the time you’ll at least give yourself a chance to win.
