If we've learned anything this off-season, it's that 'reports' about the Jays have literally zero value. They are made up BS almost 100% of the time, even from somewhat respected reporters.
I wouldn't be surprised at all if we never made a serious offer for Alonso and were just being used as a pawn in negotiations with the Mets, like we have seen with countless other players. Alonso also could have been used as a pawn in our own negotiations with Vlad Jr.
