The Betts extension/signing is a totally different issue.
You, yourself, was not for paying Betts what he wanted, so how can you now count his post-signing value and contract as something in the plus column? Something we lost?
The fact is, we lost a season of Betts, which turned out to be a 60 game season, and we got 5 years of Verdugo plus a couple not-so-promising-anymore prospects.
Grading the trade is difficult, because the results are not in for our return. The results are in on the Betts side of the ledger, though.
Speculating on what else we might have gotten for Betts is fine, but I've heard nothing about other "what ifs."
