My opinion is that the people who are "defending" Callahan are the typical very nice Nebraska fans that we all know and love. We're a state full of nice people, and nice fans, and we have a hard time really talking ill of a person. To many it seems overly harsh to criticize the guy, so they "put the best construction on everything" surrounding him and his time here.
I can dig that. I think it's admirable. Maybe I'm just not a big enough person to do that, or maybe I'm just too wrapped up in my brand of fandom to emulate them.
I don't have any animosity towards anyone defending Callahan, but I will be realistic about who and what he was to this program.
One great thing I'll say about Callahan that I continue to appreciate is the Breast Cancer fundraising he did with Football 101. I don't know if he is the coach who made 101 a fundraiser, but I do know that it was under his regime, and Bo continues it today. I find that very admirable about Callahan.
