WI parent--Did the WM poster hurt your feelings?
Last three years has not been any rivalry between these two teams...
How about the 15 years before that?
Not sure what you mean by saying "Last three years has not been any rivalry between these two teams...".
Personally I do not like looking to the past. I prefer to look at the upcoming season. Maybe look at a year or two as some of the current players were on the teams over the past two years. But, if you want to look at ancient history a more relevant time frame would be five years. Over the past five years WM and WI have played each other seven times.
West Islip has won five of the past seven games. The series is tied at one and one over the past two years. The only game that matters is the next one.
