Sorry, but blaming the loss on the OTs or really any one facet of the game is a bit short sighted. It was 100% a team loss, though the defense did better than any other part of the game.
The truth of the matter is that this OL is the best we've had in years and that includes the OTs. They were good enough to get us to 17 wins this year and the superbowl. Does the mean they couldn't be improved? Nope, but they were still good and not the liability the OP makes them out to be. Remmers will probably be replaced by big Daryl (whom I think is going to be an absolute stud) and Oher is reliable enough to get us back to the superbowl again, but if Gettleman does happen to find us a VET LT (which, if we're serious about getting back there this year is the only direction we should go if any change is to be made to LT) then cool.
if we are looking at the fix to get us back to the superbowl this year being an LT we pick up in the draft, we're going to be disappointed. you won't find that guy outside of the first 5, maybe even 10 picks and even then finding one that is ready to start at a high level right out of the gate is rare.
What we have is what we need....continuity on the OL. Changing out more than one part of that OL would set us back probably half a season unless we were able to pick up a couple absolute studs who perfectly fit the blocking scheme and we're in place by the earliest OTAs.
It's true that one might fall through the cracks and Gettleman could pick him up, but I wouldn't count on it.
The biggest issues to address is DE and the secondary. I think Early is ready to the over, but there are too many long term question marks in the rest of the group and in the secondary we have two old vets and one high priced FA that might hit the road. Aside from that, though, with Benjamin comin back I think we aabsolutely have all the pieces in place for us to go back and actually win it all next year.
I've said before (as if that matters) that the reaso not we didn't come home with a Lombardi wasn't the personnel, it was that the moment was too big for us and we made uncharacteristic mistakes that I think were rooted in nerves. All we needed to do was do one more tim ssomething that the Broncos offense couldn't do at all, and that was get into the end zone. and if it wasn't for that fumble cam lost that resulted in Denver' s only score we would have won that game ( not to put the blame of the loss on cam).
Point is that this team, as is, was good enough to win it all this year. They were good enough to have a perfect record, but their two lone losses this year can come back to not the other team being better, but our team not having their heads where they needed to be. And this is a good thing because it's the issue that is easiest for this team to fix.
any changes in personnel (aside from maybe losing 24) is essentially gravy.
