Seven teams have won the NCAA tournament without a single defeat to mar their records. Their stories include some of the most storied names in basketball history: Bill Russell. Frank McGuire. Lew Alcindor, John Wooden, Bob Knight... these teams finished perfect seasons by taking home an NCAA championship. It is worth noting, though -- all of these teams turned the trick before the tournament field expanded to 64 teams in 1985.
I realize we all love our Orangemen, but I can't imagine our current squad being compared to those all time great teams, even if this team is coached by an all time great coach. If we were to go undefeated, I think it would be a great thing and a wonderful feather in JB's cap, but I also think it says something about the declining state of the game. I think the consensus here is that there have been more talented SU teams in the past, including the recent past. I'm sure others here can be far more eloquent than me about this issue, but I think you get my point.
