I think that pass rushers tend to be one of the later developing positions. There are so many moves, so many counters to learn and perfect... Then there is the added weight and musculature that comes with growing into your mid twenties.
It pains me when some FFL playing poster snottily says, "but he didn't get many sacks in college, the stats say he's no good." So many of them quote stats and that's about it. The ones who go deep into the analytics are the worst about this. It's like a mental patient with schizophrenia-- they are trying to tie concepts together that are only tenuously connected.
All of this plays into their narrative that this is a weak Edge class. They focus on the lack of sacks, and in a truncated Covid season no less, and try to make the claim that these guys aren't any good.
I realize that part of this is exclusively due to the fact that they want to draft offensive backs, and that no excuse will go unused to tear down the competition, but it just gets old.
This is a good class of pass rushers and edge setters, but like drafting all edge players, it comes with a boom/bust risk.
