There's no irony, this is scheduled ahead of time. The press knew they were getting Parker after week 4 since the beginning of the season. BF was made available last year during our impressive stretch of being the worst offense in the country. He will be made available again later THIS season as well. Just later in the year. You might recall last season when he was made available and gave the famous "what's the upside" quote right? He's going to get his time in the hot seat.
He doesn't dodge anything though. He takes orders from his boss... just like most of us who are employed by someone. He sat down for 3 hours to visit with Chad Leistikow for a podcast during the offseason last year and the year before that. You should take a listen, he's very humble and knows that he isn't doing a good enough job at Iowa. That doesn't mean that he's going to run away from the challenge. Iowa football means more to Brian Ferentz then I am guessing anyone who roams this site.
but...I get what you are saying, I just don't think you fully understand how they make position coaches available at Iowa. I also am not saying that BF shouldn't be made available or that he shouldn't have to answer to the press. I think he should. He will, so I am not that worried about it. His time is coming and I think he should have to answer to it more than Cade (but Cade is fine too because he's now being paid to play at Iowa and is our starting QB, comes with the gig).
