No clear cut #1-
My Plumber, NOVAs, Rossiter Raiders, and Church Raiders have all won 2 titles. My Plumber, NOVAs, and the R Raiders have also each played for a third title, but lost. The Canes (Lazy Sundae) have won a title and been to the semis each of the last 2 years. You also have to mention the Lions. Although they have not won a title, they have played in the title game in each of their first 2 spring seasons. All of the other teams compiled those records over years of playing. Everyone else has to do something first before respect will be earned.
Ok that being said (some records go back 10 years) the 2 best teams as of right now...Has to be the NOVAs and the Lions with the Lazy Sundae a step behind.
