The three loudest factions of this Mariners debate are; 1. the Mariners should have traded Haniger last winter, 2. Seattle must trade Haniger this off-season, and 3. the Mariners cannot trade Haniger this off-season. But the overwhelming truth is that there are major issues inside all 3 arguments.
Let’s start with the first argument, that GM Jerry Dipoto missed a major opportunity not trading Haniger last winter. There are obvious faults in this logic, the biggest of which is the assumption that the offers were rolling in for Haniger last winter. They weren’t.
By all accounts, only one team seriously engaged the Mariners in regards to a Haniger trade, the Atlanta Braves.
