What you posted is a drop rate% stat which has injected subjectivity on who rated/decided what is a drop.
That is the context that has to be analyzed on whether the drop falls on the QB, WR or offensive scheme.
The one I posted is a simple raw catch rate stat for Aaron Dobson which shows a catch yes/no without the context of drop blame and is a more objective look.
Dobson's college catch rate stat was more consistent as shown by Aaron Dobson pro-Patriots catch rate%:

Good receivers will probably have a consistent rate ~65% overall catch rate and good catching technique for the football.
Hamler has shown neither a consistent catch rate or a good catching technique on the game tapes that I have watched.
IMO, he is overvalued as 2nd round pick for us as a receiver, but I do think he has speed which could be valuable to the team.
