Yes, because catches are an input stat, and like all other input stats are not very useful in determining how good a player is. If you make the top 10 in career receptions without ever putting up good output stats, you are the definition of a compiler.
This is just something that you've made up out of thin air. We all have our own opinions, but I don't agree at all here. You're basically inferring that 1-trick pony deep threats with nothing but straight line speed are superior. I mean, 1 catch for 80 yards is better than 5 for 70, right?
Welker isn't asked to put up 16ypc. He runs a lot of routes that terminate towards the sideline or with him coming to a stop. Sure, it's easier to line up in the slot in man coverage and get open, but Welker does it with an ease and consistency that no one has ever replicated. You put him in the slot and give him one of 4 routes to run and
no one in the NFL can cover him consistently. Given that no one in the NFL can do it, it's likely that means there's no one in the world that can do it. He's just too quick. You put him in the middle of the field in man coverage and it's impossible to prevent him from getting open with any kind of consistency. It's not like he's some slow plodder who gets left uncovered as a check-down. He's absurdly quick out of his cuts.
The notion that catches are just a compiler stat and touchdowns, the most variable and unpredictable of all statistics, are ever-important is one I can't agree with.
