do you think Pelini is the guy? Unless you answer "Yes, absolutely" then get back on the carousel. If you know a guy is not 'the guy' then why keep him? If you knew your spouse was wrong for you after a couple years, do you get the divorce or say "well, there hasn't been any abuse, so lets stay miserable?"
Stupidest thing I've seen posted all night. You keep him because, among literally dozens of other reasons, going through the process of finding and bringing in a new coach takes time, hurts your program in the short run, and has no guarantee of certainty that it will be any better. What is with all the absolutes on this board tonight? Not knowing "yes, absolutely" that Bo is the guy does not mean that Bo is certainly not the guy.
Tom Osborne was almost run out of town after his first few years here. By your argument, we should have fired him and brought in someone new. How do you suppose that would have worked out?
