When you're down to your 4th and 6th string CBs being your primary CBs, that will happen. To any team..
It doesn't explain O'Brien, MAC and the Offense s**tting the bed, but it definitely explains the defense.
Mac's Passes were late all game. That led to one of the Ints. The Pats not using Bourne opposite Parker is a mistake. It didn't make sense when the Pats were down 28-3 to be running the f'in ball. That's on O'Brien. And it didn't do the offense any favors.
One of the biggest issues I've seen this year is that Mac isn't hitting his receivers in stride. They're being forced to stop to make the catch or twist in a way that it forces them to slow down. So, at best, they make the catch and get stopped.
