With there being 80 div 4s this season, it works out to around one in five this season, but yes, it is definitely worth considering.
I'm banking on most teams having a crack though, and I expect that a season 1 tanker will have a huge advantage over a team that goes for it in season 1 and fails.
The dilemma I am having is whether it is worth going for it early to collect the 50k a week from the cup.
