Jenkins was a really good player, no doubt. But Jarius Wynn has more tackles, though 1 (count it) 1 less sack. Wynn just doesn't get any love. We tend to over estimate the impact a player had after they are gone. I've said it before and I'll say it again. Jenkins was only healthy one of the past three years. Others mentioned how we won a number of games last year without Jenkins. He is good, but the team has the tools to replace him.
Stats be damned, I've watched them both and it's not even close.
That being said, Jenkins is being asked to just rush the passer almost all the time. Seldomly he has gap responsability. It's kind of why they've been run over by everyone.
And it doesn't mean it wasn't the right decision to let Jenkins go, they factored age, durability, depth, cap room and contract extensions when they made that decision, and their track record is quite good.
But it's clear as day that Jenkins, so far, is being sorely missed.
