I expected this response; so allow me to explain what might, on the face of it, sound ill advised.
First, Burnett's STUFF has not been as much of a concern as his emotional makeup. IMO taking him out of New York, particularly in a trade for what he might consider a nobody or two, almost certainly will act as a wake up call AND a fresh start in an environment that he is better able to handle.
Second, my suggestion that the Yanks would be willing to eat all but 10M of his salary for the last two years
on his contract did not come out of my rear end. MLB trade Rumors posted this last Thursday http://www.mlbtraderumors.com/aj_burnett/
Though the Yankees currently have $1-2MM to spend on a designated hitter, they could free up cash by dealing A.J. Burnett, Jon Heyman of CBS Sports tweets. Burnett has $33MM remaining on his contract, and it would be a surprise if the Yankees free up more than $10MM via trade.
I think the Yankees would see moving him as addition by subtraction.
Third, while I agree that Guthrie MIGHT have more trade value at the end of Spring Training or in July, I also know that any prospects we get for him will be at AA or lower since most teams at that point are looking at AAA prospects as potential solutions for the season. I'd rather us be able to acquire a AAA pitcher and/or position player that could gain some ML playing time this year than some players we couldn't expect to see in the majors until next year at the earliest. One possibility for Guts that doesn't seem to get much attention is Boston. I think they will sign Oswalt but they will still have a hole in their rotation. Guthrie would only be a #4 or 5 on that team BUT he is a PROVEN commodity in the AL East. Please name one other pitcher of his caliber or better than is available and has made his bones in the A L East. Boston almost has to fix their starting pitching now that the Yankees have made their upgrades and Guthrie might have a better year in Boston than Kuroda has in NY.
Does anyone disagree with any of this? If so, why?
