Who's the bigger bust? John Lackey or A.J. Burnett?

Lackey by far, his ERA is currently over 7, that's what $15Mil buys you. What's worse is the move went against common sense, sorta like signing Mr. Glass JD Drew to a similar contract. Lackey has always been complete sh!t at Fenway or when he's not deceiving the world behind Mike Scioscia's gimmicks.
