number of times. Currently BYU is 1.5 games ahead of SMC. That means if BYU wins out they get the 2 seed regardless of what SMC does. Here's the various possible scenarios:

BYU finishes 2-0:
BYU gets 2 seed regardless of how SMC finishes the seson

BYU goes 1-1 with loss to Gonzaga, SMC goes 3-0
SMC gets 2 seed due to better record vs Gonzaga

BYU goes 1-1 with loss to Pepperdine, SMC goes 3-0
SMC gets 2 seed due to better record vs San Francisco (both 1-1 vs Gonzaga; Pacific and Pepperdine both skipped for comparison due to unbalanced schedules)

BYU goes 1-1, SMC goes 2-1
BYU gets 2 seed due to better conference record (this is the single most likely final outcome)

BYU goes 0-2, SMC goes 3-0
SMU gets 2 seed due to better conference record

BYU goes 0-2, SMC goes 2-1, Pacific finishes 3-0
I believe BYU gets the 2 seed due to being 2-1 in head-to-head of the 3 teams, SMC is 2-2, and Pacific is 1-2.

BYU goes 0-2, SMC goes 2-1 w/ loss to San Diego or Santa Clara, Pacific doesn't finish 3-0
SMC gets 2 seed due to better record vs Gonzaga

BYU goes 0-2, SMC goes 2-1 w/ loss to Gonzaga, Pacific doesn't finish 3-0
SMC gets 2 seed due to better record vs San Francisco (both 1-1 vs Gonzaga; Pacific and Pepperdine both skipped for comparison due to unbalanced schedules)

SMC goes 1-2
BYU gets 2 seed regardless of how BYU finishes.

Overall odds of BYU's final seed based upon odds for winning each game:
BYU 2 seed: 87.75%
BYU 3 seed: 12.25%

In recap - a 2-way tie for BYU and SMC would be really bad for BYU who would lose such a tie pretty much 100% of the time. However, odds of a 2-way tie taking place between them is only 12.25% at this point in time so it more than likely is something we won't have to worry about.
