So it's the word "voluntary" that you're struggling with right? It has to be. Nobody is under any contractual obligation to be there. If Lawson wants to spend this time with his newborn, good for him. He'll be here for mandatory minicamp, training camp, preseason, etc. He'll have plenty of time to catch up, and I'm sure these guys who haven't been here have been at least in the playbook. Stop comparing this to the real world.
