Hard to answer due to what is considered *most success*
For Kase success would be making it through a whole season
Ritchie - Heinen ---20 goals
Kuraly - being a sold PKer and 8+goals
Lauzon - solid defender, PKer
Vladar - different standards
If all played the same position and were the same type of players, it's much easier to come up with a standard to measure them by
So going by what I would consider the biggest success, would easily be Kase making it through a season without another head injury and being forced to retire
