I think that's the conclusion most people have - he's apparently very big into organizing team social events, or at least was in Toronto - and is really funny, but he's reticent and his grammar can be a little bit odd for someone who's obviously a native English speaker. But yeah, not being gregarious = locker room cancer; being gregarious = locker room cancer; being neither = being a locker room cancer. I'm not sure if the Toronto media approves of anyone's personality or lack thereof.
