You're probably right, but UPL's metrics are so far off league median that if Reimer gives you anywhere close to that, we get enough extra wins to be in the playoff race.
Edit: Stated otherwise, of goalies that have played 40 games or more, the median goals saved above expected is 13.4 (Dustin Wolf). UPL is -9.4. if we had 22 less goals against we're in positive goal differential at plus 3.
