But he showed in the pre-season NAB Cup and in the VFL for the Demons' affiliate Casey, where he kicked 39 goals in 14 games, that he was ready to make an immediate impact at the top level next year.
"To have a guy of his stature that's been involved in the footy club for 12 months and been playing in the VFL, where he played particularly well, I think he gets a jump on a the draft picks from this year," Roos said.
"He wants to earn his spot in the side and that's what he needs to do."
Hogan is set to draw immediate comparisons with Boyd, who is all but certain to go to Greater Western Sydney with pick No.1 in Thursday's draft.
"Where would (Hogan) be in this year? Pick one, pick two, that's what I'm hearing, but that's irrelevant for us as a footy club," Roos said.
"He's a hard trainer, he works hard and has got the respect of the players, so hopefully he's there round one next year.
"If he is, it'll be because he's trained really well and has played well through the pre-season and he hasn't just relied on that natural talent."
The 195cm 18-year-old has been compared to Matthew Pavlich and Jonathan Brown.
