The answer is none. But we all know the problem isn't that simple. In an age of salary caps and egos, investments such as the one the Packers made in Conway speak louder than actions. If Conway were to be released, the Packers would have to eat not only a big chunk of change but also their pride. Sometimes the former is easier to do than the latter.
Pride can also work the opposite way.
Take Verba for instance. The offensive tackle held out of his first NFL training camp for 22 days, ticking off the coaching staff and front office in the process. But he has shown more spunk in the last two weeks than a left tackle has exhibited in Green Bay for the past 12 years. Robinson and Townsend each started their NFL careers when Verba was entering the fourth grade. Now the Packers are presented with another problem.
