He’s missed almost two complete seasons and has suffered five confirmed concussions. It’s a tribute to Sam Shields’ talent that the Los Angeles Rams have signed the 30-year-old cornerback, giving him a chance to come back and make the team. When Shields was knocked out of a game against Jacksonville September 11th, 2016, he had suffered a second severe concussion in a 10-month period. The symptoms lingered and he decided to sit out the 2017 season. One scout says he is still a long-shot to return and it’s not clear if he should even want to come back.
