Let's take a look at the Packers' salary cap space to see if they have any money for in-season player acquisitions.
The Packers' cap space fluctuates over time and depends on many factors. Some things can be accurately foreseen and quantified. For example, during the summer all teams know they are going to pay 16 players to be on the practice squad and that most of them will make exactly $207,000 because the CBA no longer allows teams to pay whatever they want to PS guys. Non-veterans have to be paid exactly $11,500 per week, which equals $207,000 per year.
