The San Francisco 49ers haven’t put an emphasis on the cornerback position for a long time — or at least that’s my read on the situation. For years, the team seemed to roll with whatever was available at the position, giving guys like Kenneth Acker and Keith Reaser far more playing time than expected.
Sometimes it worked out. Tramaine Brock was a homegrown talent who was very effective. Perrish Cox was even good for a little bit. The 49ers actually were fairly decent at the position for some time, but I can’t say for certain that had anything to do with them making smart moves.
