Yes i thought that Kurtz was earmarked for "Northampton" but i suspect the longer that things dragged on over the winter, then Kurtz would have run out of patience and needed to get his 2026 calendar sorted out, so had to stick with BV.
As for the current predicament, perhaps as Peter Oakes suggested recently, Northampton could be helped-out, by way of being granted "special dispensation". For instance, being allowed to try and sign a rider (of suffiently good standard) who is only required to ride in home matches. Whilst this wouldnt solve the problem of being vulnerable to heavy away defeats and a poor attraction, maybe a little flexibility with guest rider averages could be allowed with the proviso that those riders do not appear in heat 15?
