3rd place should be split or better yet have a tie-break for the 4 who lost THIS WEEKEND.
A loss is a loss. To say that because a guy (who lost his teaser) wins over the other guys, because his game was on Monday?, is ridiculous. I'd say by that logic then, since each of the 4 losers did win one half of their teasers, you should then give 3rd place to the guy whose one WIN finished first.
Your logic is flawed here.
Come tues morning you have 4 guys that lost and are tied for 3rd
Have them either split the 500 or play it off.
