I have a 12-team long term keeper league (been around since 2002). We're allowed to keep 10 guys. My bubble players are Jon Lester and Ryan Howard. I have Billy Butler, Cliff Lee, Sabathia, Chapman as keepers already. Being offered Round 12 for Lester (which equates to picks 133-144 in the draft). Should I trade him for a 12th round pick? Same question for Howard with 13th round. Thanks in advance for advice.
