There is a mistake in the WPI regional. During the regional the last qualification match was not counted when the data was saved into FMS so the version that is out on the FIRST site isn't the final version that was used for alliance selections, which were re-done after the error was realized. The match can be found here:

That would bump 2791 to 7th seed 5th alliance captain at WPI. And 190 would also be bumped up to 6th seed 4th alliance captain. This would mean 2104 would not be the #5 Alliance captain, but instead was the 8th alliance captain. Below is the list of the alliance selection of WPI with teams in order of captain, 1st pick, 2nd pick.
