The field last year was pretty good. You had a top, top level team in Houston. A solid NCAA team in Dayton. A few high major teams that were either on or at least near the bubble. And even a pretty decent mid major in North Texas.
The key to those tournaments is winning a first game. Because if you lose you might end up playing the weaker opponents, where even just a single W might put you in line to play some decent teams. So looking at last year, Dayton got LSU the first game (won), St. John's the second (won) and Houston in the final (lost). St. John's beat North Texas the first game, lost to Dayton in the second, but still ended up with Utah in the third place game, and that win on a neutral site helped their resume.
Whereas Wake lost their first game to Utah, so they got Townson game 2 (not helping anyone) and LSU the third game.
