I agree with everything you are saying here.
Let's just remember how the "bridge year" comment was received: people freaked out, the media freaked out, and the Sox responded by moving significant players and money to get Crawford and Gonzalez. It served the purpose of making all those who complained about the 'bridge year' comment be quiet for a year or two, but it didn't accomplish the goal of actually bridging anything.
It was ownership and LL who walked back the bridge year comments, even though a bridge year could have been exactly what the team needed to be in the best shape longterm.
They could have waited a year, signed Adrian Gonzalez, and kept Kelly, Rizzo and Fuentes. That would have given them trade chips if needed or a legitimate 1B backup to Adrian Gonzalez (Rizzo has continued his 2011 AAA success after moving to the Chicago system: .371/.421/.629/1.050 in 27 games after .331/.404/.652/1.056 in 93 games last year) and another arm to look forward to for 2013 and beyond (Kelly has started off nicely in AAA at the age of 22 and was a top 100 prospect this year).
Fans should just understand that bridge years are sometimes necessary and allow the FO to do what is needed, rather than acting all entitled. It's the sports equivalent of a forest fire. It replenishes and is a part of a natural cycle.
The reality is that this year might be a bridge year, but the FO would never say anything about it because the media will freak out.
For what it's worth, bridge year doesn't necessarily mean they give up on the season. It just means they are not going to do things that hinder the longterm success of the club for short term gain. If that's the case, then they will probably wait for injuries to recover and not be eager to package guys like Middlebrooks, Lavarnway, Barnes, Xander, etc., for anyone.
