Someone posted a graphic that Parsons and Garrett by far have the highest pressure/double-team rate in the league this year (or something similar to that). So I don't think Green Bay is regretting trading for Parsons. They may regret it if it doesn't turn out to be a Charles Haley move, but right now, he's doing his job, getting pressure and drawing extra blockers. I don't know why our fans are so insistent on acting like he's not one of the top pressure players in the league.
I'm glad we got Houston, because this year has shown that without Parsons, we can't get much pressure with just our front four, but I have no doubt we'd be a much better pressure team with Parsons. Don't think it would change the results so far (at least not much ... maybe we win that Green Bay game), so I'm not saying the trade is why we are 2-2-1.
