The San Francisco 49ers have had a very, very odd road to their current group of offensive linemen. They went from having arguably the best line in the league with three first-round picks invested in it back in 2014 to arguably one of the worst over the past two seasons.
Losing Mike Iupati to free agency, Anthony Davis to retirement, Alex Boone to free agency and then ... Anthony Davis to retirement again certainly hurt the team big time. Couple that with consistent injuries at the center position and the fact that Joe Staley has been the only consistent player, and things have been looking a bit dire.
