I wasn't meaning that is why he would be replacement level...I was just pointing out that on top of how bad he was this year changing leagues will add another adjustment. The types of pitchers and quality of pitchers don't mean much, but how you are pitched to does change from NL to AL. Also, being less familiar with a certain pitcher does make a difference...is it a big difference, no, but if he doesn't improve on last season he could be dipping further below where he was. Changing leagues will have like a 1% impact on him and might go away fairly quickly.
I wouldn't do the trade first of all because even when he was good I just didn't like McCutchen and 2nd...Vlad Jr will be more valuable over the length of his contract vs the 2 yrs from Cutch.
