49ers Thin Position No. 2: Cornerback

Just because a team adds players to a position doesn’t automatically translate into that position being deep.

Such is the case with San Francisco’s cornerback depth chart, which at least retained starting-caliber options in Jason Verrett, K’Waun Williams and Emmanuel Moseley. And, at least to a lesser extent, an OK reserve option in the journeyman, Dontae Johnson.

But Verrett has a lengthy injury history, having missed all but six regular-season games between 2016 and 2019, while Williams missed eight games last year.

Moseley has bounced back and forth from the starting lineup the last two years.

The 49ers could have used an earlier NFL Draft pick on a cornerback, instead using their second of two third-round selections on cornerback Ambry Thomas, who’ll probably be pegged as the No. 5 option on the depth chart, while fifth-round rookie Deommodore Lenoir could round out the depth chart.

Thomas, however, opted out of his 2020 collegiate campaign and should be considered awfully raw, while Lenoir lacks the quick twitch to serve as a starting-caliber option right out of the gate.

That’ll essentially leave four cornerbacks capable of filling a major role this season.

And if one of them suffers a lengthy injury, the Niners may find themselves scrambling for options.
