NCAA Tournament First-Round Best Bets: Top 3 Picks Based on Historical Betting Trends
🏀 First-Round Cheat Sheet
Steve Makinen‘s NCAA Tournament first-round betting trends through Chat GPT and requested the three Best Bets based on the data.
These three spots show the strongest alignment of historical trends + market inefficiencies:
Under: South Florida–Louisville (163.5)
Multiple systems converge: high totals (70.5% UNDER), First Four carryover (73.1%), AAC trends (64%+), and #6 seed UNDER (81.5%)
Even the head-to-head series has gone UNDER 5 straight
👉 Why it matters: Early-round totals are still inflated—this is a classic pace + pressure spot.
Fade the #5 seeds (Target: McNeese State +11.5 vs Vanderbilt)
#5 seeds: just 40.9% ATS over last 16 tournaments
Favored by 6+: 34.5% ATS
#12 seeds: 76.5% ATS surge
👉 Why it matters: This is the most consistently mispriced matchup in March—public loves the favorite, value sits with the dog.
Lay it: Michigan -31.5 vs Howard (or similar 1-seed blowouts)
Double-digit favorites: 56% ATS
#1 seeds laying 25+: 59% ATS
Big Ten vs mid-majors: 85% ATS
MEAC teams: 25% ATS in this round
👉 Why it matters: NIL has widened the gap—true mismatches are producing more blowouts, not fewer. |
