Short pa ses might keep the chains moving, but it's the deep ball that dominates the highlight reel. , I'm examining deep throws (pa s attempts of 20-plus air yards) from the previous season to determine the league's best based on Next Dale Murphy Jersey Gen Stats' data. To qualify for this list, a player had to have at least 30 deep pa s attempts in 2020, and to filter out the best from the rest, a pa ser rating of 100.0 or better on deep attempts was required.As you'd expect, I was left with a strong group of qualified pa sers, but there are some notable omi sions from the top 10. The first one that leaps off the screen (and will likely attract an avalanche of angry tweets) is the absence of perhaps the league's top quarterback and most exciting deep pa ser: .Allow me to explain. We relied on a group of metrics to rank the qualifying pa Hank Aaron Jersey sers. Chief among them: completion percentage over expectation (CPOE), which represents the difference between a pa ser's expected completion percentage (determined by evaluating a number of factors, including pre sure, time to throw, distance of attempt and separation between targeted receiver and nearest defender) and actual completion percentage. A positive CPOE indicates performance above expectation, while a negative difference indicates performance below expectation. Mahomes ranked last in CPOE among the QBs who met the aforementioned statistical requirements, with a mark of -0.7 percent.The Bobby Cox Jersey talent around Mahomes could be working against him when it comes to CPOE. A key part of determining expected completion percentage is the separation of a receiver from the nearest defender at the time a pa s arrives. A quarterback equipped with receivers who are excellent at creating separation figures to suffer in this regard because he'll have more expected completions than your average QB. With targets like , and , Mahomes' situation becomes the perfect storm to produce a negative CPOE, even though we all know he is an excellent pa ser. As they say, speed kills, but it also can significantly hurt a quarterback's CPOE.This is primarily why Mahomes -- who posted a 107 pa ser rating Dansby Swanson Jersey and 12:2 TD-to-INT ratio on deep pa ses -- didn't land on this list. It's e sentially a requirement to end up with a positive CPOE to make the cut. If a quarterback isn't at least meeting expectation on deep throws, I'm not going to include him in the top 10.And finally, coming in on the low end of downfield attempts can hurt a quarterback's chances of earning a spot here, as well. posted a 100.9 pa ser rating, a 5:2 TD-to-INT ratio and a CPOE of +4.2 percent on deep throws, but gained just 514 yards (last Phil Niekro Jersey among qualifiers) via those attempts. He ended up just outside the top 10 along with and Mahomes.All right, enough with the explaining about why certain players didn't make the list. Let's get to the top 10.
