This guy will cost me around 10 bills a year once he's in arb2. Is he worth it? That's debatable.
And I would say defense is underrated in this game. I often see owners wonder aloud on World chat about how their pitchers are underperforming. Then you look at their SS, 2b, CF and 3b, and you know immediately why their pitchers are underperforming. While 3b is the least important defensive position of the four, your pitching staff will definitely feel a poor performer at 3b.
In Moonlight Graham this season, I had one of the worst offenses in the World, but still won 89 games with pitching that, based on their ratings, we're slightly above average. However, due to superb defense, we ended being the third best pitching team in a mostly neutral home park. Obviously, my team there is still a few seasons away from being ideal and a highly defensive focused team is not my ideal team, but they certainly got the job done this past season. They were the best fielding percentage team in the World and had the best fielding +/- ratio.
