I don't think anyone 'hates' Boise.... It's more along the lines of believing that teams that have to play LSU, Alabama, Florida, Arkansas, Miss. St., Georgia, South Carolina, etc. every year back-to-back-to-back-to-back-to-back, get tired of hearing Boise St. fans complain about how they deserved to be playing the national championship game every year because they managed to go undefeated playing the likes of San Jose St., Idaho, Fresno St., Utah St., etc...
It's a lot different when you literally have to bring your "A" game every single week, or your a** will get beat.
Boise has proven they can play with the Oklahoma's, Georgia's, Virginia Tech's when they have an entire offseason to prepare for that game, or a month of preparation leading up the bowl game. It's a little different when you're getting physically beaten up every week, and only have a week before you have to get physically beat up again.... and again... and again... and again..
I have respect for Boise's program, but playing a WAC or MWC schedule and going undefeated isn't exactly worthy of a national championship game. Nor is going undefeated in the Big-East.
But just to prove that it's not just 'hate' against Boise, everyone inside the SEC understands that the SEC East is just as irrelevant. Nobody from the SEC West is all that impressed with a win over Georgia.... their coach has been on the hotseat the last few years for a reason.
The worst team in the SEC (Ole Miss) blew out Fresno St. last year, and just went on the road and beat them again this year. Fresno St. has been considered a skin on Boise's wall...
