Simply comparing playoff records doesn't give a complete picture because it doesn't take into account the strengths of the teams that the coaches were working with. For example, George Seifert was 10-5 in the playoffs during his career while Tony Dungy is 5-7. But Seifert's teams were obviously much stronger, on the whole, than Dungy's. By my count, Seifert's teams were the clear favorites in 11 of those 15 games.
Of course, it is to Seifert's credit --- at least to some extent --- that his teams were such heavy favorites. That means they were great teams, which is evidence that Seifert is a good coach. But that's not what I'm trying to measure here. What I want to know is: what coaches have done the best job of winning games they weren't supposed to win in the playoffs?
So here's the methodology:
1. look at every playoff game since the merger (1970--2004)
2. make an estimate of each team's probability of winning that game (details below for the
crowd).
3. for each coach, add his team's estimated win probability for each game. This gives the number of games he was "supposed to" win.
4. count up the number of games his teams actually won.
5. compare his actual record to his expected record.
For instance, George Seifert's actual record was 10-5. His expected record is also 10-5. So he did no better and no worse than expected. Likewise, Dungy's actual is 5-7 and his expected record is also 5-7. So he too, has been neither a good or a bad playoff coach (at least according to this methodology).
Here is the full list (more fine print follows):

This formula is based on a logit regression of all playoff games since 1970. Try it out, it gives answers that are fairly reasonable in the majority of cases.
