Congrats to Louisville Holy Cross. Good team and very deserving.
One could debate on what makes a better tournament of double elimination vs. pool play then single elimination, but that is not the point.
The point is, the tournament was planned as pool play then single elimination, but changed to double elimination due to weather, and the reason given was fewer games and quicker tournament.
With all due respect to those commenting on this thread and to those running the tournament, and maybe contrary to common belief, but with 16 teams and 4 fields, double elimination takes longer. It's not number of games that is significant, it's number of rounds of games. Look at the attached bracket and you'll see that double elimination would take 10 (or 11) rounds of games with 4 fields. Pool play then single elimination would only take 9 rounds of games (6 for pool play + 3 for single elimination with 8 teams).
And that's before the consideration I mentioned previously, that pool play allows for long games and short games within the pool to balance each other out, where as double elimination makes it dramatically more likely for delays because it can effect all subsequent games in the bracket (as seen over the weekend).
The pool play also can easily eliminate teams having to play 3 games in a row, as mentioned above.
So, either the implication of the change wasn't understood, or there was some other reason (like being able to get down to a single elimination easily). If it's the former, then they shouldn't be running this tournament, because of lack of tournament knowledge. If it's the latter, then they are just deceitful and shouldn't be running this tournament.
