Isn't the arena they are playing in spacious?
And for the first game, then, especially, when the shooters are not entirely acclimated, doesn't that sometimes hinder teams that rely on the 3 pt shot and favor the teams with good front lines?
Also, teams that are vulnerable to foul trouble... can Bell stay out of trouble dealing with 4 strong bigs from NC? Can Silva and Thornwell against Zaga? NC can survive foul trouble other than Berry, Zaga can, too. When a key player has 2 fouls in the first 5 minutes like happened to KU and Kentucky and several other games, it changes everything.
These issues point to the favorites, Zaga and NC.
