Cornerback Leon Hall has signed with the 49ers, a source tells Adam Schefter of ESPN.com (on Twitter). There’s no word on the terms of the deal yet, but it’s likely a one-year pact for a prorated portion of the minimum salary. 
Hall, 32, worked out for the Niners a few times this year. After watching the secondary struggle for more than a month, they’ve finally called on Hall for some veteran help.
After nine seasons with the Bengals, Hall joined up with the Giants last year. The corner appeared in 12 games (two starts), totaling 20 tackles, one forced fumble, and one interception. He’s no longer a higher-end starter, but Hall can be a regular contributor, particularly for a team like the Niners.
San Francisco saw three cornerbacks — Ahkello Witherspoon, Asa Jackson, Rashard Robinson — leave Sunday’s game with injury at various points, so secondary depth is certainly an issue. Hall, with his ability to play both safety and corner, will pad the club’s roster for the time being.

I guess adding anyone to that secondary isn’t going to help. Crazy thing to me is all the money and trade chips we had this off season and we did nothing to help the secondary and instead actually let some players go that made us worse. We badly need to fix the secondary and O Line this off season if we plan on ever being better. I know Hoyer isn’t the answer at QB but when the guy hardly has time to throw you can’t put all the blame on him. I hope the front office realizes they need to fix the line and secondary and gets it done, can’t say we don’t have the draft picks and money to do it because we do.
