Quarterfinal weekend has arrived. That figures to be incentive enough for fans of collegiate lacrosse to take notice. But in case there are some that need convincing, there are compelling reasons to watch all of the games, even — or perhaps especially — the ones that are sequels.

Rematches tend to be inevitable at this time of year, of course. Teams with championship aspirations are encouraged to assemble strong schedules, and the universe of elite programs in Division I men’s lacrosse, though larger than it was just a decade ago, remains finite. Two of the four quarterfinal contests feature opponents that have seen each other before this season.
