Don't look now, but the Dallas Cowboys are ranked 12th in sacks. It happened very quickly, and I don't wish you to be alarmed. So, allow me to tell you again. They are top half in the league in getting to the QB in 2016.
How about this one: In December - a span of 4 games for every team in the league, the Cowboys are at the top of the NFL in sacks with 14 (tied with Joey Bosa and the Chargers at the top, if you want to get technical). Now, that should remind us that September through Thanksgiving also happened, and during that span, the Cowboys were at a far more normal spot of 25th in the league.
