I think all these guys are good players. Judon and Brown are better than good. Going to be interesting to see how the Ravens prioritize each and what type of money it'll take to retain them. I think you can make a good argument for most any combination.
Judon isn't better than good though. He is a good pass rusher. Thats it. He isn't good against the run. He isn't a good tackler. He isn't good in coverage. And he disappears completely for long periods of time, even full games. Better than good players don't do that.
Judon has 3 things going for him. He's a good pass rusher. He is super versatile. And he knows this system inside and out. I'd offer him $10-$12m per year. If he walks he walks. Give me a tackle with the ability to play either side at a high level over the above average pass rusher who is a liability in every other aspect of the game.
