Ok, while fair to say this BYU team is not on the level of Clemson, Alabama, or
Georgia, beyond that it gets murky. Ohio State is probably also fair though would be nice to see them play this year before knowing for sure.
Looking at the rest of the top 10 there are several teams I think we could have a good shot at beating. I don't think UNC, Notre Dame, Cincinnati, or Oklahoma State have shown impressive enough to say we could not beat them this year.
I agree that NY6 is a good goal for this team based on what we have seen this year. Would be great for the program.
However if it comes down to the end of the year and teams like those I mentioned above are being argued for the playoffs, I don't think you can dismiss BYU off hand based on quality of how the team looks and has played so far this year. Resume comparison would keep BYU out, but those other teams don't look significantly better.
