I'd say Packattack12's post by far and away nails it with why I think hiring Barry would be a mistake.
It's kinda disappointing that there aren't any other names we're looking at besides Barry and Evero. You just feel like there's gotta be others out there that are being overlooked.
Now, regardless of this next year's output, no I won't be calling to bring back Pettine. He obviously didn't have what it took to get our defense to the SB, and that blown play in the nfccg is going to stain his career till the end of time. But the whole point of letting him go is to get, or at least try and get a big upgrade. Barry definitely doesn't seem to be that based on anything he's done before.
Yes, Evero has some huge question marks about how good he could be. Hell, the chances of him failing are probably greater than him succeeding. But you still got a chance he could succeed because he's a blank slate so far in his defensive coordinator career. LaFleur had that same risk, but we took it despite his inexperience because we knew he might bring fresh ideas into the camp, and his potential to be successful was worth it.
With Barry, it just seems like you got one of the good old boys, or someone who's just here because LaFleur knows him. Now, I don't want LaFleur making decisions that reflect what I or any other fans want. He does know, or should know things I don't. But we cannot settle for just average, or even just good when it comes to defensive coordinator hires here. Barry's defense is going need to take a massive leap over Pettine's, or you're damn right I'm gonna jump all over it.
