I'm just saying spending in the top half the league and most of that money going to active roster isn't an example of a team that refuses to operate financially. You may think it does, but whatever.
2nd - Milton Williams was the No. 1 defensive FA available - IR 3.5 sacks to date. 2nd was Zac Baun who later confirmed he wasn't seriously thinking of leaving Philly. 3rd was Josh Sweat, has 11 sacks but Cardinals defense isn't any better. 4th, 5th, and 6th were CBs (Ward, Reed, Davis) Davis has been really good. The other 2 up and down.
The point? Adding all those players would have gotten them a defense good enough to overcome the under performance of the offense. IF the Bengals just sign Trey and don't sign All top 6 defensive Free Agents they aren't trying? Is that your point? Because not 1 of those players makes a big enough impact alone.
