I think it's too simplistic to blame any 1-2 elements on our recent performances. I'm not a fan of either Pees or O'Brien, but I'm also a realist. After 8 years as a top contender, we've been raped at the coordinator position time and time again. If we get anyone that shows ANY ability at that level then they get picked up at years end, usually taking a few other assistants with them.
Hell, even mediocre talent like Mangini get swooped up. This leaves us we people like the one we got, who are novice (for this level), or young and inexperienced. The one thing we had during our SB run was consistancy at this position. We've lost that and it shows. That's a product of our success. The only other team that has had long time success (Indy) over the same strech had much more consistancy at this position. It just caught up to us this year. It's a product of success in this league.
Add to that a few other factors (some preventable, some not), and you have the recipe for what we are in the misdt of..... a sub-par year where if we make the playoff's, we are one and done at best. Some other important elements that can't be dismissed.
1) Defense - Young, inexperienced and leaderless. Yeah, we went from old to young and these guys show it. There certainly is talent out there in some of the young guys, but lets face it, these guys will struggle all year. There future has not arrived yet. Perhaps BB did it too drastically (all in one year), but it was a move that he had to make. You can't argue this.
2) Off-season moves - Galloway and that other clown didn't work out. hardly gambles since they had the pedigree's, but not having them leaves us with no #3, which really limits what this offense can do. Letting Gaff go, in hindsight, was not wise. Plus the Seymour trade.... we all know why we made it, and I still think in the end we'll be better for it, but this has really hurt this defense this year on the field and in the locker room.
3) Injuries - As always. We have some key ones that are really effecting the product on the field. This will always be the case and it is what it is here.
This is just a few issues out there, there are more.
So yeah, it's partly the coordinators.......... but there is a bunch of other stuff happening that's exposing the reality of success at this level.
