He absolutely could, but this isn't a championship year. So if EB is the guy and the team responds, we win 2 or 3 games we wouldn't otherwise and end up picking 17th instead of 7th in every round of a good draft.
Or it goes the other way and craters, EB loses the room, Howell's OC guidance falters and his season and the offense as a whole either plateau or regress.
But the most likely scenario is that it ends up making no real difference. EB, left with the scattered remnants of the firings, can't really do much to elevate the team, has a ho-hum HC debut that clouds his value versus other candidates, and all it adds up to is midseason drama that shifted focus from a plucky, competitive, evolving team to the behind-the-scenes dysfunction that this organization and fanbase knows all too well.
Unless something really egregious happens, firing RR midseason is a bad idea.
The Snyder move is "Let's focus on our worst elements immediately, putting them front and center when we should be focused on playing football."
If you believe in EB then you should want him to become a head coach the right way. Chosen by a GM with real consideration, input into the formation of his staff and the draft, then a full offseason and camp to prepare, implement systems, and make a debut that's representative of everything he has to offer as a coach.
It's true that we have nothing to lose right now. But we also have so little to gain. This season wouldn't amount to much more if we resurrected and installed Lombardi himself. All it would do is start unnecessary midseason drama, put undue pressure on a coach that's already adjusting to a job he's never really had before, and put a stark ending to the tenure of a guy that they clearly like and respect regardless of his failings. And for what? So we can win a couple more this year, maybe? What trophy does that get us?
The urge to tinker when you're frustrated or angry or convinced that the path you're on is wrong somehow, even though you're focused on what's right at the tip of your nose instead of what's down the road a bit... That urge is a powerful thing.
There's an old quote from The West Wing...
"A new pilot will fly into cloud cover. There’ll be no visibility. And they’ll check their gauges, they’ll look at the artificial horizon, it’ll show them level, but they won’t trust it. So, they’ll make an adjustment and then another and another… He said the number of new pilots who fly out of clouds completely upside-down would knock you out."
We know we're going to clean house after the season. We know the offseason is when the most and best coaching and GM candidates are available. And we know that we're not competing for anything this season regardless of what we do. Our deadline deals made our outlook and priorities pretty obvious.
We have flown into cloud cover. We're level. We just need to be patient and stay the course.
