The question is actually invalid, because both Essendon and Carlton have won the most at 16 premierships each. Therefore, the next team will have won the third most AFL Premierships; and that is Collingwood. The Collingwood Magpies have won 15, but they have lost many more grand finals than they have won!
Hawthorn have won ten Premierships. The years that Hawthorn have won, is in: 1961 1971 1976 1978 1983 1986 1988 1989 1991 2008

In this season, 2010, Collingwood has won only the one Premiership in the past 50 years - that being in 1990, under Lethal coach, Leigh Matthews. However, Collingwood are certainly set for finally breaking through in the Grand Final this season - for their 2nd Premiership in the past 50 years. Next week will tell.
