I don't think this has that much to do with what Champ and the other CBs got. It has to do with Law watching Lawyer get cut a week before the season began w/out a moment's notice. Law has been pretty adament that he doesn't want something like that too happen to him.
Also Law is in no way worth a 1st IMO nor a 2nd. I'd sent a 3rd and 4th or 3rd and 5th to NE for Law and nothing more. Probably just a 3rd. I would also not send LAllen b/c the Cowboys Defense is already solid w/out Law but the OLine is weak even with Allen.... I don't make a weakness worse to make a strength stronger.
