The hottest Sports Analytics Substack posts right now

The top four #1 seeds (UConn, South Carolina, Texas, and UCLA) dominate the title odds this year, accounting for about a 93% combined chance to win.
UConn is especially dominant and undefeated with a very high COOPER rating, so early-round upsets against them would require something to go very wrong.
Still, strong contenders like UCLA, Texas, South Carolina, and LSU could challenge in the later rounds, creating the potential for exciting matchups even if upsets remain unlikely.

Projections now use a new COOPER power rating blended 5/8 with Ken Pomeroy’s ratings, and the model runs 100,000 simulations to better handle injuries, travel, and how teams perform during the tournament.
Forecasts are updated once per day after games and include region-by-region chances, game win probabilities, point spreads, and a spreadsheet archive; the East region analysis is free while the rest is behind the paywall.
March Madness is still highly unpredictable — recent upsets (like Florida losing) have meaningfully shifted odds in regions such as the South, and the chance of a perfect bracket is basically zero (around 1 in 10 quintillion).

Treat live bets like zero-day options and favor underdogs: capture flow-driven slippage by betting more when odds lengthen, avoid hedging against your own positions, and use cash-outs or offsets sparingly.
Construct parlays with a clear game "script" and correlated but independent legs: stick to 3–4 legs that are likely to resolve early to get leverage while avoiding simple coin-flip combinations, and remember books will dampen obvious same-player correlations.
Manage risk first and know when to stop: be extremely risk-controlled until you’ve grown your bankroll, don’t chase losses or bet against your own views, let volatility work for you, and walk away when returns hit diminishing margins.

Norway dominated the 2026 Winter Olympics with a record 41 medals and an outsized per‑capita performance.
People in Norway favor outdoor, nature‑based activities like walking, hiking, and cross‑country skiing and tend to train more at sustainable tempo and threshold intensities (Z3–Z4) with less time spent at maximum effort.
These activity patterns appear across the whole population, suggesting Norway’s success comes from a broad, inclusive sports culture that emphasizes fun and steady training rather than early specialization.

The Billy Beane-led ownership group at Toulouse had to relinquish control of the club because they won too many games last season.
Toulouse's alternative, analytical team-building approach led to unexpected success, including winning the French Cup.
Success in sports, particularly when driven by data and analytics, can sometimes lead to unexpected consequences.
