Yes, I'm on the planet. I know Baylor and Gonzaga have great offenses. That's why the total is set so high. I can find more reasons, though, to go Under rather that count on both teams to hold up their high offensive standards. 
Baylor's tremendous defense in the NCAA Tourney is getting overlooked. The Bears have held their five opponents to an average of 60 points. 
Gonzaga has an above average perimeter defense. UCLA hit a blistering 58 percent from the floor against the Bulldogs in scoring 81 points during regulation. That was highly unusual. I don't see it happening again. The Bears held their previous four NCAA Tourney foes to an average of 64.2 points. 
This is a neutral court matchup with the game being played at spacious Lucas Oil Stadium, a converted football field with a difficult shooting background.
