My thoughts are
The issue has nothing to do with getting rider's, it's cash. Nobody is interested in riding for the Scrimping Stars or the Peanut Panthers.
Not sure Sheffield, Ipswich or Belle Vue will suffer the same problems if injuries or poor performances arise.
There has to be 4 - 5 points Danes, Swedes or Germans out there to take a punt on needing rides. The other issue is, clearly Allitt's phone only has about 14 rider's numbers in it, plus Holder & Batchelor's deleted.
