I think it's not fair to say Breslow botched it because I don't believe he really wanted Bregman here long term anyway (see: last offseason chatter, short term deal with opt outs, etc.).
I think it's fair to say that the Sox botched it IF they really wanted Bregman (by this I mean the Cora, Sam leaning portion of the FO). Per all reports and what we have seen, he was Plan A for 3b and they have now fallen down the path towards several contingency plans which appear to be lesser than. It's a botch if they can't figure out 3b/2b with expediency (entire FO botch). If they have to give up additional prospects that they weren't planning on giving up in order to bring someone else on, it's a botch.
It's a FO botch if they continue to have a roster that makes no sense (4 OFers AND Masa). This is a botch that goes back a few years. It's fair to call out multiple people for this.
I think it can be both a botch and yet not a botch. The Schrodinger's Cat of botches. Honestly, we may not even have a clear answer when the full squad reports on the 15th.
