Cubs almost have to go out and see if they can sign some kind of veteran starter from the free agent pool if they have any shot of competing in a 60 game season right? If this was a normal season or even a 100 game season I would be OK with trying out Mills or Rea for that spot but after Darvish and Hendricks you have to be concerned about the decline Lester showed last year and the inconsistency of Chatwood then to add to the mix another pitcher without much to show for as a starter in the big leagues you can't just give away games at the back end of your rotation like that when nearly every game is going to have a big impact on your playoff chances. Guys still out there looking for a team include Tyson Ross, Marco Estrada, Clay Buchholz, Jason Vargas, Matt Harvey, and Andrew Cashner all who have a lot of MLB experience starting games. I don't know what their asking prices are or for how many years but Q and Chatwood are free agents after this season and Lester has an option year too so even if you have to offer a 2 or 3 year deal to 1 of those guys there is a need for the rotation starting next season too.
