I think everything written here is subjective at best.
Statistically it’s almost impossible to prove a players impact at a position like Simmons.
“Hearing his name” is not a good way to judge impact. Generally speaking, the times you hear a name, it’s putting something in the statistics category.
As mentioned, drawing a double team is not statistically quantified. Drawing that attention allowing for another guy to get mentioned.
I saw you mention Autry before and I agree he is also a stud. Having Simmons, Autry, and Tart means one of the best DL in the league. Super important when you need that to beat these top QBs like Mahomes. The pass rusher with those guys may be an issue still pending Landry’s return and I agree, probably overpaid for what he offers. More likely a product of Simmons/Autry than a top pass rusher.
