I don't see how you can milk NFL concussion protocol. You're either cleared to practice or you're not.
written test and computer test. maybe some Adderall.......
I've heard of players purposely doing poorly on the written/physical test to stay in the concussion protocol. Not only that, but all you'd have to say is "I have a slight headache this morning" and boom, you're still there.
Pulled muscles and concussions are tough to ell the severity
