I listened to this live as I listen to every game on the radio, plus the postgame.
Eddie P. and Ferentz have had similar conversations regarding practicing well not meaning you'll play well - the context about the team having a good week of practice. They talked about that both for Ball State and Iowa State - good week of practice and then playing poorly in the game. That is why Eddie P. made that reference regarding Beathard - it was a 'refrain', if you will, from prior similar conversations.
The whole context of this 'didn't play well in practice' isn't as bad as some are making it out to be. It is odd as Ferentz typically doesn't say something 'negative' about a player publicly. That being said, saying someone didn't practice well on Thursday is pretty vanilla as it comes to being criticized.
The entire context of Ferentz talking about Beathard was extremely complimentary.
If someone thinks this was Ferentz taking a shot at the 'fans' I don't think they listened to the interview and are really reaching. I don't think Eddie P. was defending Beathard either.
