If it were to be implemented, there would need to be some sort of criteria for the option to be taken whether it be x amount of games or something else. I'd deadly consider it considering how crap my player is despite the number of seasons I've played.
I've already said it's not going to happen. Corbin for example would have absolutely no incentive not to retire because he doesn't make any one day teams anyway. Given I've said already that one of my goals for this season is to make one day cricket here more professional and try to get people take it more seriously, I can't think of anything stupider than implementing this.
There is'nt enough of or any correlation between actually being a better FC player after retiring form OD for it to be even considered anyway imo.
