I suppose it could happen.
Even given the generally weak teams they've played, what's been extraordinary is the inability so far for teams to put drives together, and string 1st downs against the D.
The D has given up 3 TD this year, (3 TDs in 7 games!) and 2 came on 1) a missed tackle 65-yard run and 2) a tipped pass 64-yard TD catch and run.
Mayfield is the type of QB that has given them some trouble in the past, and I'm not predicting the Pats D can shut-out a team with as many offesive weapons as the Browns, but I suspect a Baker's dozen might be a reasonable estimate for this coming Sunday.
I like doughnuts.
