If you only want to count wins or losses and disregard anything else change
the formula to

=IF(B2="","",COUNTIF($B$2:B2,"Win")/SUM(COUNTIF($B$2:B2,{"Win";"Loss"})))

do the same and copy down the formula as long as you want

That worked awesome! thanks so much.. One follow up question, occasionally
there is a tie- how can I enhance this formula to take out those ties so
its
not counted against their teams win % ? thanks

First of all 2 wins out of 3 is not 75%, it would be 67% if you round it
to
the nearest
percentage or 66.67% if using percentage with 2 decimals. Anyway assume
the
data starts in B2,
format C2 as percentage and put this formula there

=IF(B2="","",COUNTIF($B$2:B2,"Win")/COUNTA($B$2:B2))

copy down as many games you expect and it will return a blank when B is
empty
