Grimsby Town vs Shrewsbury Town
Our model puts a Grimsby Town win at 65.4% in this League Two fixture — the clearest call on this fixture. Expected goals run 2.14 to 0.88.
What this probability has been worth
A number is worth what it has been worth. Across 1,564 predictions published before kick-off and scored against the result afterwards, the calls we priced between 65% and 75% came in 70.4% of the time — 135 fixtures in that band. The model claimed 69.3%, so the two are within 1 points of each other. In this range the stated probability has meant roughly what it says.
Where we disagree with the market
Bookmakers price Shrewsbury Town at 4.7, which implies about 21.3%. Our model has it at 14.7% — 6.6 points lower. That is a wide gap, and it is worth being plain about what it means: it is not a claim that the price is wrong and we are right. It means two methods that usually agree have landed far apart on this one, and only the result will say which of them read it better.
A high-scoring home side
One model here does nothing but estimate how likely the home side is to score four goals or more, and on this fixture it reads 60.9%. Across our settled fixtures that happens about 8% of the time, so this is well above ordinary. It says nothing about who wins — a side can score four and still be caught — but a match where one team is expected to run up a total is one where the scoreline is much harder to call than the result.
