A couple observations. Let me preface this by saying I like Bo, and Paps for that matter. However, liking guys does not necessarily mean they are the right guys for the job. And, I'm not saying Bo is not the right guy for the job but, I am reserving judgment on that.
1- Bo is a firey, low tact type of guy. Old school football coach type if you will. That doesn't bother me at all. Being the HC at a D1 program like Nebraska is much different than most other professions where that type of behavior is frowned upon. I've worked with guys like this, my dad was a bit that way, and I can also be a dick when presented the right opportunity. I am sort of tired, really tired actually, of all the whining about Bo yelling at coaches and players. Passions run high in the middle of a game. These guys are big boys- they can handle it (much better than some fans obviously). Praise in public is always a good thing but criticize in private may have to fall by the wayside on the sidelines. Bo has these guys backs and they know it. It is obvious that the players like him. Please let it go.
2- Paps appears to be a nice guy. Sorry but that isn't a compliment for a DC. To some extent the players reflect the attitude of their coach. IMO the last thing you want on the defensive side of the ball is a congenial, timid, nice guy attitude. I have been trying to come up with the name of a well known successful defensive coach that wasn't a hardass and I am drawing a blank. I would bet there are a few but I think you get my point. Paps is in a sort of catch 22 position. He isn't/wasn't qualified for the job yet he has it. And, sure Bo is responsible for him being in that position but, if he is going to be the defensive coordinator, regardless the conditions, he has to be able to handle the repercussions when his unit isn't performing. That many substitution penalties is not performing. I don't blame Bo at all for blowing his stack over it. This isn't coffee klatch at the local church so grow up and welcome to the jungle.
Hold these guys, Bo and Paps, accountable for the results and performance on the field all you want but, can we stop with the sniveling about the angry faces, yelling, and sideline behavior. It's all just a little too wimpy for me. /rant
