Webster's doubters definitely didn't like the command, that's for sure. He has improved in that area, but he still needs to prove it for a little longer. You don't bail on Doubront in early May, especially after getting shellacked by one of the best teams in baseball. He's out of options and will definitely be claimed on waivers by 29 other teams. I think you give him at least until June 1. If the flashes of dominance are gone and he still cannot hit the side of a barn with the heater, then you cut your losses.
In terms of Lee, I don't see them even entertaining the idea since trading for him would put them over the lux tax for 2014, which is a critical year to stay under the lux tax. I could see them dealing for an innings eating back end of the rotation guy.
