This is about the player, NOT the trade (e.g. Herschel Walker).
MVP-caliber players whose greatness was already established, who still had a significant amount of value left. Traded!
Gretzky’s got to be near the top of this list.
Kareem Abdul-Jabbar to LA.
Roger Clemens did pretty well for the Yankees.
Players at very ass end of their careers who accomplished little with their new team (Jerry Rice).
Draft day trades (Elway).
Players who hadn’t established themselves yet (Favre).
