Posada had a season for the ages. .330 20HR 80+ RBI. I agree, he was completely irreplaceable this season. He was awesome. But even the biggest homer in me wont consider that he'll continue that pace. Prior to this season, Posada was a .260-.280 type hitter who would hit anywhere from 18-25 HR. I think he reverts to that OR WORSE next season since he is a catcher with TONS of mileage and approaching 37. ANd with the season he had, he could easily get a 4-5 yr deal worth 15mil a season. I dont think that is worth it, especially for a catcher who continually catches 135-145 games a season. It just isnt.
As far as Mo is concerned. I love the guy. Love him. He is the biggest reason for our success, and that is without a doubt. But he has shown chinks in the armor for the past few yrs, but he has staved them off. One of these days, that armor will crack and he will become mortal. And at 38, it will come soon. If we could nab both of these guys in 1 yr deal, absolutely, sign them up. But we'd be commiting 7 figure yearly salaries for guys into their 40s. This was kinda the root of the whole problem that started this run of futility anyway. You can always "pay for it later". Well later is now and I'd rather take a back seat for a yr or two than have these weigh us down when the team is young.
