Two things:
1. It was a short contract. You can live with underperformance for a one or two year deal.
2. He helped bring us a WS title. That makes it worth it, much like the decimation of the farm.
So, in a strict and literal sense, no, he wasn't worth it. In a broader sense, the answer is yes. I liked the Moreland signing when it happened, and I still like it. I would do it all over again. That is my kind of signing.
