I ended up picking team 4 due to having more 50-100 RPI wins but it's hard to choose without knowing final scores and if it was a home/away game. I'm one that doesn't care if a team loses to bad teams a couple of times if they show they are capable and have beaten tougher opponents. I would say team 1 and 4 are ahead of the other two with the info dealt to us. Overall record doesn't matter as much as the top 100 RPI record.
After further review, it looks like St. Marys only has 21 D1 wins. Their resume is pretty poor. Their best wins are BYU, Harvard and Santa Clara. I think all 4 would be out...
