Is Rollin allowed to win SOTY this year?

No it can't

Unfortunately, there's this thing called eligibility period

I don’t think it is eligible for it

Not eligible

No they're not eligible for sorry because the song is old , but their next comeback is, so people should hype up their comeback to have a chance to be nominated.

They might win the best discovery award which would be well-deserved

No. It's the release date that matters.

Right, GDA? Excluding Dec 2010 from the awards to take out IU's Good Day.

Why not? If it deserves

No, it came out 4 years ago.

it can win SOTLFY
