re: Swope Had At Least Four Concussions in College and Never Missed a Game?

He was a 4 year player at A&M so it's possible that he could've had a mild concussion, maybe once a season, and as long as he passed any concussion tests/evaluation afterward been allowed to play the next week.

The frequency could hurt him with the issues the NFL is facing right now in regards to lawsuits over concussions though.
