Giant Killers is back for our 14th annual metrics-based forecast of big upsets in the NCAA tournament bracket. As usual, we're analyzing each Giant vs. Killer game in the first round.

Our statistical model yields an upset probability for each game, based on both the Basketball Power Index of each team and on the stylistic factors that have most often led to tournament upsets in the past.
