There are many statistics that can tell us the rate at which different teams can get to the quarterback. For this article I am using pressure rate, which is a compilation of all hurries, knockdowns, and sacks. Pro-Football-Reference.com does a great job of keeping track of this. Pressure rate is the most accurate representation of how often a team has an effective pass rush despite factors like missed tackles and defensive style.
The teams with the two highest pressure rates so far this season are the Chiefs at 29 percent and the Jets at 28.4 percent. The Jets however achieved this bringing a blitz at half the rate of the Chiefs. The Jets accomplish this by only rushing four but disguising their rushes. The Chiefs have an obvious advantage over the rest of the league in bringing the blitz as they do not have to play Patrick Mahomes who is only blitzed at a rate of 18.1 percent over his career and 14.3 percent this season according to CBS. Since he has entered the league, Mahomes stats against the blitz have been almost unreal. This is because, despite the blitz, most of his throws are not pressured due to quick reaction time and a quality offensive scheme. Mahomes along with all the other young talented quarterbacks in the league have forced defenses to adjust.
