Grimsby Town vs Northampton Town
Our model puts a Grimsby Town win at 68.4% in this League Two fixture — the clearest call on this fixture. Expected goals run 2.25 to 0.84.
What this probability has been worth
A number is worth what it has been worth. Across 1,941 predictions published before kick-off and scored against the result afterwards, the calls we priced between 65% and 75% came in 69.9% of the time — 183 fixtures in that band. The model claimed 69.4%, so the two are within 0.5 points of each other. In this range the stated probability has meant roughly what it says.
Where we disagree with the market
Bookmakers price Grimsby Town at 1.71, which implies about 58.5%. Our model has it at 68.4% — 9.9 points higher. 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.
The ratings gap
Grimsby Town carry a rating of 1507 against 1403 for Northampton Town, a gap of 104 points. On our scale that is the difference between a side that controls most of its fixtures and one that has to earn each of them. It is also the single largest input into the probabilities above.
Northampton Town are off their season peak
Northampton Town peaked at 1500 this season and sit at 1403 today, 97 points below their own best. Measuring a side against itself rather than against the table is often the earlier signal, and it is not visible in a league position.
