First Round Matchups on Thursday

Matchup Probability
No. 9 TCU @ No. 8 Ohio State 44.2% / 55.8%
No. 13 Troy @ No. 3/4 Nebraska 12.4% / 87.6%
No. 11 South Florida @ No. 6 Louisville 37.8% / 62.2%
No. 12 High Point @ No. 5 Wisconsin 20.4% / 79.6%
No. 16 Siena @ No. 1 Duke 1.9% / 98.1%
No. 12 McNeese @ No. 5 Vanderbilt 14.8% / 85.2%

Beyond these outright win probabilities, today’s point spreads and totals offer plenty of exciting trading angles for us. The No. 9 TCU vs. No. 8 Ohio State matchup features a tight 2.5-point spread favoring the Buckeyes, with an Over/Under total set at 146.5. On the complete opposite end of the spectrum, AP No. 1 Duke is a massive 27.5-point favorite over Siena in a game with a 135.5 total.

If you use your initial $10 trade on today’s heaviest favorite—the Duke Blue Devils at a 98.1% implied probability—a winning trade yields just pennies in profit. Conversely, taking a swing on the biggest underdog on the board, Siena (1.9%), would return a massive payout if they manage to pull off the ultimate upset.

When evaluating today’s most competitive matchups, the stats reveal some fascinating edges. Ohio State (RPI #49) hosts TCU (RPI #57) in an absolute nail-biter. OSU flipped a switch in March and boasts a slightly tougher strength of schedule (0.5549), but TCU’s David Punch has confidently stated his squad’s physicality will win out over height.

In another intriguing clash, battle-tested No. 5 Vanderbilt (26-8) meets a dangerous No. 12 McNeese (26-5) squad, complete with a viral pregame feud between Vandy’s coach and McNeese’s student manager. While McNeese boasts a stellar #30 RPI, Vandy owns an impressive 11-5 record against top-50 opponents. McNeese is 0-2 in that same high-tier ranking range.
