Oh Rex Ryan, you lovable loser.

The Buffalo Bills coach is a Chicago Cubs fan, and told reporters he rented a bus and traveled to Cleveland with several staff members to attend Game 7 of the World Series on their off day.

Ryan saw his Cubbies jump out to a big lead, then blow it in excruciating fashion as the Indians rallied to tie the game and force extra innings.

However, when rain delayed the game at around 11 p.m. local time, Ryan and his group headed home. After all, they had a trip to Seattle to prepare for.

"I hate to admit it," Ryan told ESPN.com's Mike Rodak on Friday.

The rain delay was 17 minutes. 17 MINUTES!

He missed the Cubs break through in the 10th inning and win their first World Series in 108 years.

108 YEARS! That's like the last time the Bills beat Tom Brady!

And poor Rex didn't have FOX Sports Go, or a working radio on his bus, so he had to get the news of the Cubs' victory from a much less reliable source: his brother.
