I mean you're just wrong about this. 2024 stats (both played 16 games, although Karlaftis played 96 more snaps):
Sacks - Karlaftis 8.0 / Rousseau 8.0
Pressures - Karlaftis 37 / Rousseau 35
TFLs - Karlaftis 9 / Rousseau 16
I know stats don't always tell a black and white story but how can you look at that comparison and tell me Karlaftis is a "game breaking talent" while Rousseau is a JAG?
There's a tendency on this board to act like everything KC touches turns to gold. But I think their roster has been a bit overrated. Where they really separate themselves from the rest of the league is their coaching. Compared to our roster on the whole I don't think they had some massive advantage last year... And don't get me wrong, I wish we had at least one legit game changer other than Allen, and I haven't been a big fan of how Beane has prioritized certain positions over others. But he has built a roster that has a very high floor if not a high ceiling. It's a roster that has beaten KC in the regular season where it is more about matchups, but has lost in the playoffs where it is more about coaching.
If you're giving Karlaftis that much of an edge over Rousseau, and the same for the rest of the respective rosters, you're giving McDermott a built in excuse that he doesn't really deserve.
