Bo isn't going anywhere any time soon. Take a step back and try and understand the big picture. Callahan wasn't fired because of his W and L's. It was a contributing factor, but not the only one. He alienated donors, former players, high school coaches, and many, many fans. He certainly got the big star recruits but did it by telling them they'd be starting regardless of talent...which didn't always pan out. This caused more talented players to be sat when they should be playing, causing internal rifts within the team. He was either incapable or unwilling to change out personnel on his staff (mainly Cosgrove) when the D continued to decline. Despite bringing in top tier recruits they could not coach them up to standards and players consistently gave up during games, played soft, and lacked fundamentals. He sold Nebraska as a stepping stone to the NFL and downplayed the traditions, which led to the horde of prima donna players that cared more about themselves and their future careers than the team and their teammates. They also all but did away with the walkon program.
All of this led to serious damage to the program on and off the field. When Bo got here he had to repair all of that. Fixing the mentality and work ethics of the players is not something that can be done overnight, and certainly not within a year. Some players will never buy into it (ala the Offensive Line) and will just have to be washed out of the system. Others, like Suh, Crick, Asante, O'Hanlon, Dennard, Thenarse, etc. who have bought into Pelini's plan have shown the obvious improvement. A Defense that was one of the worst in the nation now a top 10 defense. The players are playing harder and play till the final whistle. Former players are back on the sidelines and love everything that's going on and the direction the program is heading.
Nobody in the Husker Nation is cheering a 8-3 season. They're cheering the progress that has been made, the repairs that have been completed. As long as Bo continues to progress until we get back to their former glory, he'll be here. Prince screwed you guys over, but believe it or not you were in far better shape than we were after Callafraud. That's why Pelini will be here for awhile yet, and that's why Husker fans are happy with him. Anyone who understands football can see that. It's more than just wins and losses.
