I need to offer something of a correction. I've been pointing out that Hooper had "only" a 50% success rate on 3rd down this season-- 9 first downs on 18 3rd down targets. First of all, that ignores a touchdown, which would make his rate 56%. But more importantly, I realized that I don't really know if that success rate is good or bad. I was assuming it was sub-standard without a frame of reference. So I pulled data on several of the top tight ends to compare. Find it below. In order, these numbers are 3rd down targets, 3rd down receptions, 3rd down TD's, and 3rd down catches for first downs. The last number is the success rate-- the % of 3rd down targets that resulted in a first down or a touchdown.
Hunter Henry: 16 targets, 10 receptions, 2 TD, 8 1D, 63%
George Kittle: 34 targets, 27 receptions, 2 TD, 18 1D, 59%
Zach Ertz: 29 targets, 18 receptions, 2 TD, 15 1D, 59%
Dallas Goedert: 19 targets, 11, receptions, 1 TD, 10 1D, 58%
Austin Hooper: 18 targets, 12 receptions, 1 TD, 9 1D, 56%
Jared Cook: 20 targets, 11 receptions, 2 TD, 9 1D, 55%
Mark Andrews: 37 targets, 25 receptions, 2 TD, 17 1D, 53%
Darren Waller: 24 targets, 15 receptions, 1 TD, 11 1D, 50%
Travis Kelce: 31 targets, 17 receptions, 0 TD, 13 1D, 42%
Evan Engram: 16 targets, 9 receptions, 1 TD, 5 1D, 38%
So it would seem that a 56% success rate is right in line with other top tight ends, and thus not something that should be held against Hooper's production.
