It's shaping up as an interesting run for No. 1 in the spring boys FAB 50 as the top 18 teams are all undefeated and untied -- a combined 107-0.

The real fun starts soon as these teams will be on a collision path -- some during the regular season, others in postseason. In fact, at least five of the current top 18 will have to lose as they compete in the same playoff bracket as other top 18 programs.

Now, on with the rankings ...
