I don't wanna be the negative one here, and really Im not, I think its a good hire. However I gotta question what this means. We are a long way off personnel wise to run a 3-4. If they do it anyway, it could be a long year for the defense, and maybe a very short year for Eli because of it. Especially if they take a QB with the second pick. Eli will end up like Warner.
In the long term, assuming Shurmur isn't fired in the first two years, Bettcher could end up being a great hire. I just question if now is the right time to completely change the D. Seems more like a long term move then a short term move.
At least he has a cool name. I can see it now, "Bettcher ass they are gonna make the playoffs." lol
