Tom Coughlin was just named #14. Seeing as Jeff Fisher was plastered all over the promotional materials, he's presumably in this list above him, unless they are using his moustache purely for markerting purposes. And ignoring that many of the other coaches on the list so far are multiple Super Bowl winners, they are interesting to compare because their first full season was the same year. In that span:
Coughlin took two different teams to Conference Championship games, multiple times. Fisher has been once.
Coughlin went to the playoffs 9 times in comparison to Fisher's 6.
Coughlin won playoff games in 5 of those appearances, in contrast to three for Fisher.
Coughlin won two Super Bowls. Fisher participated once.
Coughlin has a better regular season record by .017 points, with more wins despite fewer games.
There are probably more ways to compare the two in terms of on-field results, ignoring their off-field work. But IMO, if I were a Giants fan, I'd be pretty amused if Fisher ends up higher in the final tally.
(Not to totally rag on Fisher, but I'm finding this poll pretty funny on the whole)
