No - as per the rules, he HAS TO nominate if he wants to be eligible for a third year on the rookie list. He doesn't have an option. If we don't promote him this year, his options are nominate for all the drafts (which he would obviously do), or quit football.
Only when he's been through all three drafts and remains unselected are we able to put him on the rookie list for a third year. The same applies for Jake Spencer.
Either way, you're right in that the conundrum is the club's, not Valenti's.
