Pretty much exactly what we all could have expected. Played in 305 games (72% of the team's games), racked up 6.7 fWAR, and was generally pretty exciting, especially in 2013.
All in all, above-average play from short for ~40 million over 2.5 years at ~$6M/ WAR. If he were a free agent signing and not a trade acquisition I think people would have loved him.
