Perrish Cox reportedly agrees to deal with Titans

Former San Francisco 49ers cornerback Perrish Cox has greed to a deal with the Tennessee Titans, according to Matt Maiocco of CSN Bay Area. Cox is set to sign a three-year deal worth $15 million, according to the report.

Cox is the second 49ers cornerback to depart this offseason, as Chris Culliver signed with Washington on a long-term deal. With the biggest team needs being wide receiver, cornerback and defensive line at the start of the free agency period, San Francisco has addressed all but cornerback.

Most figured they would try and retain one or Culliver or Cox but there was very little talk about bringing Culliver back and there were reports that the 49ers didn't even make an offer for Cox. Obviously, the position is in definite need of an upgrade. The 49ers have Tramaine Brock, who is coming off an injury, and then not much else at the position. Rookies Jimmie Ward and Dontae Johnson have some potential, though.

Cox spent three seasons with the 49ers, but did little of note until he stepped in last year. He filled in excellently when the 49ers sustained injuries at the position, but he played his best football early on and was clearly being out-played by Culliver down the stretch. That's why Culliver is getting significantly more (also: Washington loves overpaying players in free agency).

Looking at the roster, I think cornerback is the only massive need. I think the internal guard candidates are solid, the 49ers need to draft a receiver and a defensive lineman, but cornerback is the only significant pressing need.
