Which free agent guards should 49ers target?

The San Francisco 49ers had an absolutely terrible offensive line last season. There was nothing good about the offensive play, even among the good players, like Joe Staley and Alex Boone. Everybody played poorly and everybody made everybody else around them worse because of it.

Nothing was quite on the level of terrible of Jordan Devey. That was its own special brand of terrible that I cannot imagine actually getting worse. The only thing that was as bad as Devey was Jim Tomsula's reluctance to move on to the better players even when it was glaringly obvious he was making the wrong decision by sticking with Devey.

Andrew Tiller took over eventually, and folks were even calling for Ian Silberman at one point. At right tackle, Erik Pears was bad and people were calling for Trent Brown. It was all a huge mess. And though Boone wasn't as good as he should have been, losing him would suck.

Oh, and the 49ers are totally going to lose him this offseason. Boone is set to hit free agency and really, the 49ers shouldn't feel good about either guard spot or the right tackle spot. There are big question marks. They'll bring in some rookies, to be sure, but free agency will likely be important for San Francisco's offensive line. Below, we'll take a look at the free agent guards this offseason.

Are you guys seeing any names on that list that make sense? Evans is obviously the big name there, but he comes at a high price and I'm not sure if he fits in Chip Kelly's offense necessarily. Schwartz is another player I like a lot, though I have no idea why he was released and how he performed this past season.

We're going to keep this one short as I don't have a ton of time today, but it looks like there are an awful lot of young players who are not sure things by any means, but who could have value for a team in need like the 49ers. What say you guys?
