After reading the quotes from Theo on Pedroia and his injury, as well as Youkilis saying he feels "stronger than ever", Ellsbury should be fine after a solid offseason of healing, Beckett has been working out with a personal trainer, which virtually means his back should be much better, and DiceK has said he's working his lower body more, which will save his arm, it sounds like the injuries are all healing up nicely. Gonzo is going to talk to his surgeon about potentially bumping up his schedule to start swinging earlier because he's ahead of schedule, so he should be good for Opening day.
From Theo's quotes, as well as the various most recent updates (other than Ellsbury - haven't heard much on him other than Theo saying he's pain free, contradicted by Tito saying he still feels it a little, but that was 2 months ago), I am extremely excited about this season and have high expectations for the injured players. I don't think they'll all average 160 games, but I wouldn't be surprised at all to see 145-150+ for each player.
For what it's worth, I don't think I'm looking through rose colored glasses, I think that's forming an opinion based on reports that have come out, which is really all that we can do.
