When the San Francisco 49ers released NaVorro Bowman a few weeks into the 2017 season, you could hear the collective gasp from the fanbase. Despite one gruesome knee injury, and later an achilles rupture, Bowman continued to be the heart and soul of the 49ers, holding the team together with the departures of Frank Gore and Patrick Willis. Bowman signed with the Oakland Raiders not too long after his release, contributed on their defense almost immediately and went into 2018 a free agent.
And now, one year later, Bowman remains unsigned.
