Frustrating would be the keyword I would use after watching back some of the key plays from Sunday's loss to the Texans.
The consistent theme to me seemed to be a lack of execution. The Patriots just didn't cover it, block it or run it well enough to win the key plays to beat the Texans and a vital game in their postseason chase.
Why the Patriots didn't execute? I can't answer that. You could certainly look at coaching, or just an overall lack of good football players. Maybe it's both.
