When the Dodgers traded for Adrian Gonzalez, they gave up promising prospects (at the time) for Gonzalez, Nick Punto, Josh Beckett and Carl Crawford. Punto and Beckett each contributed a bit, Crawford is very solid when healthy (which he never is) and extremely overpaid, and Gonzalez is still as consistent as ever.
Gonzalez is arguably the Dodgers’ most valuable player. He’s not the best by any means, but imagining this Dodger team without Gonzo is a scary thought. First base would feature some combination of Justin Turner, Chase Utley and Scott Van Slyke.
