Feschuk gonna Feschuk.
As for Kessel, while I can't provide direct knowledge, what I've been told is that Kessel just really dislikes answer the same cliched questions over and over again. That's why most reporters only get one word answer and such out of him. On the rare occasions he's actually asked something interesting, he's been known to be quite happy to answer with some detail.
Also, the whole ducking the media thing gets overblown. The media often ignores him after games because they know he's not a good quote. Also, sometimes the media in this city cross the line. Guys have waited to ambush Kessel after he's already changed and is leaving to go home. By that point, the time for interviews has long passed, and you should expect a snide response if you get aggressive about getting a guy to talk. On top of that, others in the media just make up pure BS from time to time, and sometimes, it sticks. We're generally smart enough to ignore it around here, but, if you check some of the other hockey boards, that BS is accepted as the gospel truth.
