He started 100 games at 2b, and less as the year went on. He was not an every 2b in the second of the season by any stretch.
FG has his defense as terrible; BRef has his defense as above average. I know many prefer FG, and I'm not going down that road, but his defense was not universally panned by the statistics.
Now, I will say I believe they thought/hoped he'd be better defensively when they signed him. And that he had regressed out there.
He also didn't start a game in the playoffs, so by the time the team was fully formed, he was not the starting 2b.
