Which contracts do you think have been worth it?
IMO, Matt Kemp is experiencing injury after injury and having a horrible season, Manny was traded before his contract was up, CC opted out (only to re-sign), neither of Arod's contracts have been worth it, Mauer is not even catching anymore, Tex has had nothing but injuries and down years lately.. Pujols was solid last year, abysmal so far this year and still 8 years left (at age 33? we think).. The jury is still out on Prince fielder and Joey Votto's deals..
IMO, only the investment (so far, as I said jury is still out on Fielder/Votto) that has worked out was Jeter.
