In regards to Pete being a dick...
He has a sarcastic personality at times and really can push buttons to get what he thinks is best for his program. If he thinks he needs something to make his program better, he will go out of his way to make sure that happens. Often times that can rub people the wrong way. The people who work alongside him in an athletic department (media relations, athletic training, academics, marketing, etc.) are the ones who would most likely think he is a dick and again it goes back to him knowing exactly what he wants for his program. Some people understand the nature of college athletics and how coaches are wired and can handle it. Others can't. If he were hired, I am sure that would be quite a change from how Grobe worked with others in the department.
With all that said, he is very good in the public in interactions with boosters, fans and media. He knows how to play the game and understands the importance of being involved with all aspects of the program. He is very good with his players and making sure they are student-athletes and not just there to play football. He is involved with their academic progress and knows where each kid stands in terms of grades and whether or not they are doing what they should be doing in the class room. He is good with discipline and for the most part keeping kids out of trouble and taking care of problems when they arise. He is very personable and energetic. I don't know Bz personally, but from what I have seen personality wise, Lembo is much closer to the way Coach Prosser was. I feel they share some similarities in how they operate(d) their programs in all facets.
He is a good coach and I think would be successful at Wake Forest. He is very meticulous and will walk in the first day with a plan put in place to continue to build the program back to where Grobe had it and hopefully beyond. Hopefully this is the step that Wellman will take.
