...because Kotchman is arbitration eligible and is about to get paid a ton of money. Meanwhile, the Braves would've gotten two compensatory draft picks when Tex bolted...both of which could've been worth more than what they got. For example, Mike Hampton left the Mets as a free agent after the 2000 season, and as compensation, the Mets received draft picks, one of which became this little-known guy named David Wright.
The Braves would be justified to move Tex if they got blown away by the other team. But this is no risk for the Angels, who basically get Tex for the stretch run, and if they don't sign him long term, they can use the draft picks to restock. Meanwhile, all the Braves get is the right to pay Kotchman.
Horrendous trade for the Braves, highway robbery for the Angels.
