As Patriots players were wrapping up their work day Friday, one final meeting was called. It was with the kickoff coverage unit. The Patriots struggled in that area against the Texans last Sunday, and today, they face the NFL’s No. 1 ranked unit led by Jacoby Jones. The best explanation for the struggles last week was this: 1) Too many players were getting single-blocked. The message was that players had to do better getting off blocks; 2) The Texans favored a “middle return” and coverage players didn’t play with good enough leverage against the wedge. That’s an area that naturally received a lot of attention this week.
