1. Seattle Seahawks vs. New England Patriots (2015)
This soul-crushing defeat haunts Pete Carroll’s dreams. Seattle played the Patriots in Super Bowl XLIX and was inches away from victory. They were a yard away from the Pats’ goalline when Russell Wilson opted to throw a pass. The other option was to offload Marshawn Lynch, the five-time Pro Bowl running back.

New England rookie Malcolm Butler infamously intercepted Wilson’s pass. It was a harrowing moment because many fans instantly criticized Carroll’s call. However, statistically, he made the right choice (via Sports Illustrated). But it was soul-crushing because they were so close to another elusive ring.
