The San Francisco 49ers cornerback depth chart is exceptionally slim right now, and the it appears the team is considering some options. ESPN's Adam Caplan is reporting the team worked out cornerbacks Drayton Florence and Dominique Franks.
The 49ers current cornerback depth chart consists of Perrish Cox and Chris Culliver starting on the outside. When the team went to the nickel on Sunday, Cox stayed outside, and Dontae Johnson covered the slot. Leon McFadden was the fourth cornerback, but saw limited work. Instead, the 49ers used Craig Dahl a bit more. Tramaine Brock is currently dealing with a hamstring injury, and might miss Sunday's game against Washington.
Franks was a fifth round pick in the 2010 NFL Draft, and then signed with the Baltimore Ravens this past summer. He got playing time in Week 6 through 9, getting 60 snaps in Week 8 and 63 in Week 9. It appears he was not particularly good, with PFF grading him out at -2.3 overall in Week 9, with a -1.5 pass coverage grade. In the three previous games, he was between -0.8 and 0.5. I haven't seen enough of him to say anything, so feel free to add your own thoughts.
Florence was drafted in the second round of the 2003 draft, and has bounced around the league. He played for the Carolina Panthers last season, and spent part of 2014 training camp with the Detroit Lions, before being cut in mid-August.
