His Silver Slugger Award.
Also, McCann was personally responsible for the NL winning their first All Star game since the Carter Administration.
And its easy to see how his stats were a little down this year, compared to most years. He had little protection. Chipper was awful for most of the year. And they didn't really have anyone hitting consistently behind him either. That plays a role. And McCann was banged up alot, too. And he had vision problems earlier in the season.
He still had a good year. And, outside of Mauer, he's been the best catcher in baseball the last 4,5 years. That's inarguable.
