So, definitively, which are the top 5 teams in the country?
I think you're kind of missing the point here, which is that there's not enough evidence to say definitively that Syracuse is a top 5 team.
With that said, I think Arizona and Kansas are definitely top 5 teams. Who fills in the rest of that list is still to be determined. I'd bet on Syracuse being in that group, but I don't think the schedule has provided them enough opportunity to prove that yet.
