BEHIND EVERY GOOD COACH
A round of applause for Buffalo Bills defensive coordinator Jerry Gray, who hasn't gotten enough credit for molding the Bills' unit into one that could be one of the best in league history. That's precisely the kind of pressure Gray put on the Bills in the preseason, when he talked to his players about rivaling the 2000 Ravens and 1985 Bears. Last year, Gray's defense led the NFL in takeaways with 39. In Sunday's 22-7 win over Houston, the Bills forced the Texans into five turnovers and held them to 120 total yards.
