Hopes were high for the 49ers starting cornerbacks in 2018. The team acquired Richard Sherman via free agency and had high hopes for second-year player Ahkello Witherspoon.

Sherman spent most of last season dealing with and recovering from a calf injury, and that was after an offseason of rehab following an Achilles injury in 2017. The three-time first-team All-Pro and four-time Pro Bowl selection figures to be healthy and stronger in 2019.

Witherspoon struggled this past season but showed some improvement toward the end of the year. The jury is still out on the young cornerback, and 2019 will be a good indication of where his NFL career is headed.

Witherspoon will have some competition for the starting spot across from Sherman. Tarvarius Moore started the final two games of this past season after Witherspoon suffered a sprained posterior cruciate ligament (PCL).

"We're extremely excited about Tarvarius," general manager John Lynch said on December 31. "He got an opportunity to go play, and I think he showed some really good things. But I think that's going to be great competition between he and Ahkello."

The 49ers went through several safeties in 2018 as injuries ravaged the position group.

Adrian Colbert, Jaquiski Tartt, and Jimmie Ward all ended up on injured reserve, leaving San Francisco with Antone Exum Jr. and Marcell Harris as its starting safeties by the end of the season.

Colbert went through a sophomore slump after showing a great deal of promise during his rookie campaign. The former seventh-round pick saw his Pro Football Focus grade drop from 73.1 in 2017 to 31.7 in 2018.

Tartt's season ended on injured reserve for the second consecutive year. He has played in just 17 games over the past two seasons. Each of Ward's past three seasons has also ended on injured reserve.
