It's just really hard to win the CWS. FSU has been to Omaha 23 times. They have never won. 0-23.
In this CWS, 13 games have been played and 8 have been decided by one run or extra innings, and two more have been decided by two runs. That's 8 games that could have flipped on a hit, error, strike zone, or even positioning on a single at bat. Thinking about the three WF v. LSU games, every game could have resulted in a different outcome had any one of several plays turned out slightly different.
So, yeah, it hurts to lose the final game in extra innings, when one run in any one of ten innings would have resulted in a WF win, but that is just the nature of a sport which needs to be assessed over an entire season, but the ultimate winner is decided over a handful of games. Literally anything can happen. As a result, you got to enjoy the ride. Appreciate the season as a whole. Otherwise, this sport will destroy you (ask Red Sox fans before 2004 or Cubs fans before 2016).
