ive seen different versions of this stat with KJ hamler at nearly 18% or something - not sure how we're measuring drops
it's an issue because clearly the high drop rate is a potential issue - but it just doesnt show up on film at all
the drop rate i saw had mims at a similar rate to jeudy for what its worth and on the other side he makes absurd catches on the regular
this isnt a perriman where he has bad catching technique and drops littered all over his tape - Mims has good technique and great hands - i find it really hard to reconcile those drops existing lol
EDIT: i think it's PFF's catch rate i saw and that was referring to 2018-19 i think - and i think they also have different definitions of drop
this stat you posted seems to not really factor in expected catch rate into the calculation at all
EDIT 2: found how they judge contested catches:
We try to stay as consistent as possible. Each play gets looked at over 4-5 different times by different people. If we determine that the defender was the main cause of a pass being incomplete and they were able to prevent a catch being made, we will give them credit with a pass defensed and no drop for the receiver. If we determine that a receiver was the primary cause for a ball that falls incomplete on a pass that was catch-able where the receiver was in position to make the catch, the ball hits any part of his body, or the ball goes through his hands, we will give them a drop.
to me that suggests that any receivers who are consistently being put in contested catch situations for whatever reason are going to end up dinged more than those players who rarely get put in those situations...
