I hate the years for both players, but I think most fans will tell you with Lidge that they are ok with it. Granted he sucked this year...he was horrible. However he was a huge part to them winning the WS last year so an extension was deserved. I know a lot of people thought he would come back down to earth but this past season was his worst to date. Ibanez for 3 years at his age was bad but I think it worked out fine the first year. Will he contribute like that for 2 more? I'm not so sure about that.
They have a ton of issues regarding players with contracts. I think 2012 is the year where guys like Blanton, Werth, Victorino, Hamels, Ibanez, Rollins, Utley(I think), and Howard all are up for contract. I read an article last year that the revenue they generated from the WS allowed them to increase their payroll by 15 million or so. So they might have a little more to spend this offseason again. That money however will probably go straight to player's raises.
My personal opinion is that they will try and move Victorino and plug in one of their top OF prospects. They'll probably try and lock up Werth long term...Utley and Rollins will probably re-up at a reasonable number a both seem to really like the organization. I think with Rollins that will be a club decision though. This year was dreadful so an extension is not a given with him. With the pitching; The Phillies don't offer longer then three year contracts for pitchers so I'm not sure Lee will go for that..same thing with Blanton.
Howard is the big question mark. I wouldn't move him for anything, but at his age and the money he'll want, I expect they may try and shop him next offseason.
