Tbh there wasn’t really an opening for a male pro till Kev/pasha/aj all left and Anton went to judge.
He was probably on the radar as he knew everyone and is British.If he’d joined earlier he risked being left on the bench for years.
I wondered if they held off because as the new British Pro he was always likely get a lot of attention so they wanted him to be a bit older before they heaped that amount of pressure on him.
