This time I fully agree with you that the lack of pass rush was the primary thorn in their side yesterday. But even with that glowing deficiency, they STILL could have won if they had made even a couple more tackles. IMO, they would have been in position to somehow still win IN SPITE of their huge lack of pass rush.
To that end, back in the regular season when they were literally playing guys that were signed off of other team's practice squads, I remember they were playing their 10th guy at some of the D-line or edge positions. They clearly had a run of injuries, retirements, or guys that didn't pan out. You can only play who suits up, so they did the best they could.
As for the comments about imagine-what-they-could-have-done-with-Jones-and-Collins, they were never going to pony up the $50 million to keep Collins or the $82.5 million to keep Jones. You can't pay everybody, and in many ways you can't fault them overall as they continue to be right there at or near the end of the season.
