Here's what the AJC internal newsletter said about him in March 2002 when he was hired:
Mike Knobler has joined us as a deputy Sports editor. He comes to us from The Clarion-Ledger in Jackson, Miss., where he was a sports editor. Mike formerly worked for the Savannah News-Press. A native of Pasadena, Calif., Mike graduated from Harvard College with a bachelor’s in English and American literature and language. He’s an instrument-rated pilot, a two-time runner-up in the Worst Golfer
in Mississippi tournament and winner of the Jackson Generals Media hot dog eating contest.
Sounds like an interesting guy, but nothing in there screams hockey, does it? I did find a link to an 1983 column he wrote in The Harvard Crimson about Harvard's hockey team. And another story from 1984. (Harvard couldn't have been putting their student paper online all the way back in the 80's, could they? I'm guessing they did it later as an archival project.)
Here's a link to the AJC Tech page, you can probably find some of Knobler's work there, or maybe do a search on his name at AJC.com.
