Of course they are disappointment, but realistically, a 10-3 season with a Sugar Bowl win is a great season. We had a great season last year too, we just don't have a trophy to show for it.
You're wrong on the Peach being less than the others. At this point, all Big 6 are equal. It's an accomplishment, whether you like it or not. If we had won the Orange Bowl last year, that would have been one of the highest marks ever for MSU football.
