Alex Cora was a great defensive second baseman when he was with the Dodgers. Cora-Izturis was probably one of the best middle infields I've ever seen, not that any of you guys would have noticed. Maybe he just got slow after he went to the Red Sox.
It really was a great double-play combo. I think it was heightened by the fact that the two of them were coincidentally at the height of their hitting powers, something that we had no way of knowing at the time. Many people figured Izturis would become a better contact hitter over time, but it just hasn't happened.
As great as their defense was back in the day, most of the time they weren't that much greater with the glove to make up for the holes they created in the lineup. The fact is that fielding is a smaller part of a player's value than hitting is. As much as I liked Cesar Izturis, trading him for a half-season of Greg Maddux turned out to be a good move.
