I mean, if the Cubs sign Lester, it's a huge addition to the rotation, and instantly upgrades the rotation. If they get him for a not-too-exorbitant contract as well, all the better. If they go to 8/200 and just blow him away with AAV/length, I probably wouldn't be overly happy long-term, but hey, short term instant upgrade. If they don't sign Lester, it doesn't mean they're punting the offseason, either, as there are other avenues to upgrade the rotation if Lester decides not to come to Chicago. It just ends up being more complicated than it would be to sign Lester, as there is an additional cost involved (draft pick/international bid/player trade).
