In June of 2006, the New York Islanders announced Neil Smith as the new General Manager. His tenure lasted just over a month as he was replaced by then backup goalie Garth Snow, who retired and took over the job.
That would be like if the Islanders fired Lou Lamoriello and made Thomas Greiss the GM, it's absolutely insane that it happened, 14 years later and I still can't believe it.
Anyway, it's hard to mess something up in 41 days but Neil Smith had one pretty bad blunder using revisionist history. In the 2006 draft, the Boston Bruins traded up in the third round with the Islanders for pick 71 and in exchange the Isles received picks 98 and 126.
