NCAA Tournament 2015: Upset Picks for Round of 32 and Updated Sweet 16 Schedule

The No. 11-seeded Dayton Flyers will face the No. 3-seeded Oklahoma Sooners on Sunday, and this game is my pick for the final major upset of the round of 32.     

The Sooners aren't a one-man team, but there are times when they depend too heavily on star guard Buddy Hield to do too much on offense. In the team's 10 losses this season, it cracked the 70-point mark in only two of those games.

In the losses, the Big 12 Conference Player of the Year (Hield) has made just 39 percent of his shots. He's not an incredibly efficient scorer on average at 41 percent from the field, but when he shoots the ball well, the Sooners are a more dangerous team. 

Dayton is at its best when it is defending well. In its last two games, Dayton is holding teams to just 54 points per game. With a berth in the Sweet 16 on the line, you can expect another strong defensive effort, and I believe that will propel them into the regional semifinals.

Here's a breakdown of the entire schedule for Sunday's action, per ESPN.com.

One half of the field of 16 is already set, but only one matchup is known. The only regional matchup we're assured of seeing is the No. 2 Arizona Wildcats against the No. 6 Xavier Musketeers.

The Wildcats are a long, skilled and versatile bunch. While freshman Stanley Johnson leads a balanced offensive attack, Arizona separates itself from most teams—Xavier included—on the defensive end.

Arizona is allowing just 59 points per game and holding opponents to 39 percent shooting from the field. To add another layer to Arizona's effectiveness, the team also makes 36 percent of its threes. Matt Moreno of GOAZCATS.com thinks that combination of qualities makes Arizona all the more dangerous.

Much has been made about the Kentucky Wildcats' undefeated run this season, but Arizona is on a 13-game win streak.

In that span, only three opponents have managed to stay within 10 points of them. Despite an efficient offense that has the Musketeers shooting 48 percent from the field, Xavier won't be the fourth to play Arizona close.

The Wildcats will power their way into the Elite Eight with a double-digit win.
