Agree with a lot of what's said here. I agree there issues with age in the secondary, that there's an obvious problem with the line (particularly LT), and that there should be coaching changes (although not Tomlin IMHO).
Yeah, I think some of it is obvious, and I think some is just because replacements have been underwhelming (Hood, Worilds, etc...), while some is because they've kept guys around too long while thinking there would be no slippage (Keisel, Taylor, Clark) and some is because players just aren't very good (Gay). As for Haley, either he has to go or the Steelers need to completely revamp the offensive styling to a drop/throw concept, and that means the receivers will need to get open quicker and the line will need to hold up a hell of a lot better.
I think Bell is very promising at RB (certainly "worth a damn" , and that overall we do have some younger players (DeCastro, Pouncey, Brown, Heyward, Bell, Jones) who could form a nice nucleus alongside Ben, Woodley, Timmons, etc.
Time will tell, but that 3.5 ypc isn't all because the OL sucks, IMO.
(FWIW I completely disagree about Mesko -- I think you must be thinking of Mesko the New England punter, not Mesko the Steelers punter...he was absolutely terrible with Pittsburgh, there are only so many 30 yard punts you can have before trying another option!)
Mesko the Pittsburgh punter still knew how to punt in New England, I'm guessing, even if he's having issues this year. McBriar's poor punt let Edelman get a great return and helped put the Patriots in position to put the game away. Hell, even struggling, Mesko could have done that.
I don't know if we're in better or worse shape than those years...time will tell. This year is a lost cause for sure, but with a healthier team, the development of some younger players and another talent infusion from the draft, it may not be as dire as it would appear. Things can turn around quickly in the NFL; it's proven every year (KC is the latest worst-to-first story).
I thought your team would bounce back this year, but the O-line problems killed the season early. I think people are taking yesterday's game too much to heart, because the Steelers defense had been holding up well enough prior to NE blowing them out, and NE has a habit of lighting up LeBeau's defense on occasion. Even a lot of the flaws I'm talking about are more about small amounts (slight slippage, for example) than huge drops.
There's a lot of patching to do, though, IMO.
