I'm entirely confused with your post..why are you attaching free agents with teams...lol. Boston's rotation as it stands is Buchholz, Kelly, Webster, De La Rosa, Workman. Adding Lester doesn't make it a great rotation. Scherzer to NYY would make a nice rotation, but the injury worries for both Tanaka and Pineda are high. Adding a number 3 pitcher to a team with a bunch of number 3s doesn't really change anything. Laffey? Tampa probably has the best rotation in the division, but is lacking on offense.
