According to a tweet today by Dave Birkett of the Detroit Free Press, former Bengals safety Chris Crocker could be visiting San Francisco before his travels are all said and done. Birkett covers the Lions, a team with which Crocker just finished visiting. Birkett mentioned that Crocker was scheduled to visit Arizona as well and that a decision regarding where he would sign was expected to come soon.
I find this interesting given the 49ers current depth at the safety position. Granted Dashon Goldson might not be back beyond 2012 (currently franchised), but with C.J. Spillman signed to a three-year deal this off-season it would seem the team has relative confidence in him, too.
The team also drafted Trenton Robinson in the sixth round to add to speedster and special-teams-ace Colin Jones. Mark LeGree was also signed to a futures contract after being released by Seattle last season.
Crocker would bring veteran presence to the position, perhaps something the 49ers feel is needed...at least through training camp. Still I'd guess that he won't sign if he thinks he is only camp-fodder...so it will be interesting to see.
