I know. You're scratching your head and thinking "Why on earth would I care which players on the 49ers are free agents?" Well, when coaches (like Greg Manusky) move from one team to another they often bring a few players along with them, either because the player really likes the coach or visa versa. Also....
Troy might be out because he's a little guy who's somewhat inaccurate, but maybe the Chargers like him for the back-up QB spot. I don't know. Alex Smith, hometown boy and former #1 overall pick, is a name that will not go away when the topic of replacing Volek is brought up. As much as I love the idea, I think he's going to be too expensive and will either stay in San Francisco or try and land somewhere else that offers a competition for the starting job.
Ray McDonald might be the most interesting name on that list. He's young, talented and has been pretty solid as a backup DE for the 49ers but probably has no chance of starting for them in 2011. If Manusky really likes Ray, I could see him imploring A.J. to get him to replace Jacques Cesaire as the starter opposite Luis Castillo. I don't know that he'd be too expensive either, considering his limited experience.
Franklin is a good young NT that the 49ers plan on putting the franchise tag on for a second consecutive year. He's staying. The issue with him needing that tag is that it puts the Niners in a tough spot with Manny Lawson, who has been good as a pass-rusher in San Francisco while being double-teamed regularly. If the Chargers were to try and fill the OLB spot through free-agency, I'd almost rather they go after someone like Mathias Kiwanuka, but Lawson wouldn't be a bad fit either.
Dashon Goldson, from what I've read, is thought of as a FS on the verge of being a Pro Bowler. Basically, he's Eric Weddle. I've heard people within the Chargers organization talk about Weddle being able to move down and play SS, so I suppose it would be a good idea for A.J. Smith to at least talk to Goldson....but the Niners would be crazy to let him walk.
