I feel like our offensive issues go much deeper than the OC and canning Marty halfway through the season won't change the dysfunction by itself. Granted I was one of those people who thought keeping him on was a turrible idea when it happened, but the only reason I'd be in favour of dropping him mid-season is if we wanted to give an in-house guy the inside track for next season and see how they go.
We need an offensive identity and we need to actually build around that. You can find a long list of sides that actually know what they like to do and they make their personnel fit around that (and there's a pretty strong correlation between that list and the playoff contenders). Whereas we've got a WCO OC, vertical WRs, run-heavy TEs and I'm not even sure how you'd sum up our OL. We need to make an executive decision about what kind of offence we want to have, we need to find an OC who can do that and we need to start looking at cutting or trading every player who doesn't add value to that picture (not necessarily all at once, but you get the idea). Personally I'd say that aside from Stanley and maybe Yanda, no-one's position is safe. Hopefully it doesn't take so long that our current generation of defensive players has reached and passed its prime in that time.
And I think it's time we started having one eye on Joe's successor. When his contract becomes easier to move there'll be a fair bit of literature about how new QB contracts are handled, which will help. If the right guy falls to us I'd like to see us pull the trigger, but I think it's still too early to look at giving up Trubisky-level hauls for someone or to go full Cleveland and start reaching for people who have a bit of potential. Personally I'm an optimist and I believe he's still in the tier of QBs who can win us another Lombardi with the right team around him and the right circumstances, which gives us a bit of time to make the right decision and we can focus the rebuild on the guys around him to start with. But in the meantime, is it really too much to ask for a specialist QB coach for the guy? Surely Bisciotti isn't that much of a tightass?
