I think of two very smart comments. The first repeated so many times I don't even know who said it originally or the context, but I'm sure it wasn't football. The second was by a great coach. The two comments are:
1. "Everybody has a price" - Unknown
2. "You keep your best players" - Don Shula
We gave up two Pro-Bowlers, one was Laremy Tunsil, for whom we got a ton of resources ... but still no Pro-Bowlers. The other was Minkah Fitzpatrick, who is now a 2-time All-Pro ... and we haven't gotten a Pro-Bowler for him yet either. So we've seen both ends of that spectrum. Tunsil is the epitome of the first comment. Minkah is probably the example of the second comment.
IMHO, we shouldn't get rid of Howard, because he is THE dominant takeaway guy in the league and those are rarer than pass rushers. But by the same token, he's injury prone, and he will never command a higher value than now. Personally, I'd try everything possible to keep him and keep him happy ... but in the end, even Howard has a price.
We're going through the same analysis with many guys right now, such as re-signing our key FA's Emmanuel Ogbah and Mike Gesicki, arguably our least replaceable guys on both sides of the ball. But I try to stick with the wisdom that Don Shula gave, because he truly is the GOAT. Replacing Xavien Howard is highly unlikely ... and if we're serious about being a Super Bowl contending team ... we need a few great players. I hope we find a way to keep him.
