The fact is, if this team is going to compete next year, wholesale upgrades are necessary. 1B is one of the best places to do so with the best available options, unless we want to spend similar money on a perenially injured Jose Reyes or a bit less on a 35 year old Carlos Beltran. Sabathia would also be an intriguing option, but a very expensive one, but The Tigers have shown us how valuable it is to have one shutdown ace no matter how meh the rest of your pitching staff is, of course we don't have the Tigers offense. I know, Penas a great clubhouse guy, but 10 mil is a steep price for a youth mentor. You said he has "zero business on the Cubs" next season, which seemingly implies there's no scenario where he should be on the team. I'm not saying they should sign him, but missing out on Fielder and Pujols would be a pretty good reason to do so since they have nobody to man 1B otherwise.
