Yeah that's the thing. It would be a perfectly legitimate signing in a vaccuum but it wouldn't do much for the team's outlook since Santana is unlikely to do much more than eat innings and provide below average production. That would have more value on a team with a stronger front of the rotation but when the top two guys are basically innings eaters themselves (albeit more productive ones), it's hard to get excited. Jimenez should also eat innings but he also has some upside which a least gives more cause for optimism.
