2019 NFL Free Agency: 10 second-wave free agents who could be under-the-radar bargains - Under the radar bargain
Quinton Spain, G
The Titans signed Rodger Saffold to fill Spain's role on their offensive line, which means he should now be available to somebody else. Spain has not been quite as good the past two years as he was in 2016, but he has shown the ability to reach a higher level of play than almost any offensive line free agent left out there. If you need help along the offensive interior, again, he's one of your best bets for quality production.
