I think they will want the trial to start quickly. Based on the sentiment on golo - the pool is NOT tainted as far as I can tell, but they'll likely ask for a change of venue just due to the enormous publicity - can't blame them.
I also think that BC will NOT do well in jail. I think that he'll start not being able to control his anger and resentment toward Nancy and any ability he may have had to be convincing about him "trying to save their marriage" will quickly fade as he lets the anger build. I am sure that he blames her for his incarceration - in that somehow if she'd been a better mother / wife / partner that he wouldn't be there.
Brad also seemed to define himself by his status, his job, his athleticism, his standing in the community and also liked being in control. All of these things have been taken away from him in jail. He's also likely a Type A person - and will want things to move expeditiously and might even push his attorneys or become uncooperative if he feels that things are not going fast enough. I also truly think he believes that he will be acquitted and will want to get back to his life ASAP. He'll also want "his side" of the story told - it's quite possible that getting him to agree to NOT testify will be one of their bigger challenges - as I am sure he finds himself quite convincing and will want the opportunity to "impress" the jury.
