A wild weekend is over, and bettors have had a solid 36 hours to dive into lines for the Sweet 16. Much like the NFL market, some bettors like to pounce early, while others like to wait until the day of the game.


Using the proprietary tools and data available at The Action Network, we’ve broken down the most lopsided and most heavily bet games, as well as some of the most significant line moves.

Here’s what has happened so far across the Sweet 16 betting market.

All info as of Tuesday at noon ET.

Most Lopsided Tickets

West Virginia vs. Villanova (-5.5)
Friday, 7:27 p.m. ET

Last Sunday, West Virginia received just 35% of bets as a double-digit favorite against Marshall. They opened at -11.5, but closed at -13 and won by 23 despite the lopsided support on Marshall. Villanova also won its last game by 23 as a double-digit favorite, but the Wildcats wound up with 63% of bets.

The betting trends are carrying over to this game, as 74% of tickets are backing the 1-seed Nova squad and ignoring WVU. We’ve seen reverse line movement push the Mountaineers to +5 on two separate occasions at Bookmaker, but the line has gone back to -5.5 relatively quickly both times.
