I'd have much preferred Renfroe at $7M than JBJ at even the same money, despite his poor defense in an important position like RF in Fenway.
You do seem to be "sticking up for Renfroe," and I'm not sure why you are denying you are.
To me, this debate turned into the value of rbi's then HRs vs other stats, and not necessarily "metrics," like you claimed.
OBP is not a metric. Good defense is not a metric. BA and speed are not metrics.
Renfroe had power and a strong arm that wasn't always that accurate. His arm helped mitigate some of his defensive deficiencies, especially in Fenway, but he was not as big of an overall plus, as many felt he was. At $3M, yes. At $7M, not so much.
I was fine with trading Renfroe and saving $7M, but not for a higher priced guy like JBJ.
To me, the prospects better pan out, of this was a bad trade. Unlike you, I see value in prospects, before they make the bigs.
All stars were once prospects.
