Interesting Prop on Bookmaker

[Derek2408]

FIRST UNDEFEATED NFL TEAM TO LOSE A GAME
INDIANAPOLIS COLTS +250
NEW YORK GIANTS +400
DENVER BRONCOS EV
MINNESOTA VIKINGS +350
NEW ORLEANS SAINTS +150

Am I missing something here? Literally the first team to lose wins the bet. So I first looked at the 1:00 ET games. Minnesota plays the Rams, and the Giants play the Raiders. I know, I know, there are no "sure things" but 99% sure neither of these lose. The Broncos play at 4 ET, against the Pats. I know they are at home, but they have a very good shot of losing this game. At night, the Colts play the Titans, which is a possible loss, but I'm asking myself why I havent bet on the Broncos yet. The Saints are off this week so heres what the slate looks like.

Saints off
Vikings @ Rams
Raiders @ Giants
Pats @ Raiders
Colts @ Titans

Nevermind, just looked at the Week 6 games, and the Giants play the Saints at noon. I guess it's just do you think the Pats will beat the Broncos week one, because the Broncos play the Sunday night game, therefore if they win this week you are screwed. However, any bookmaker users thinking about taking the Pats ML can find better value here at EV rather than Pats(-170), assuming you expect MIN and NYG to win SU too.
