If you have not been around for free agency in the past, this is pretty much how it pans out.

Tonight will just be a lot of guess work by the media and the fans. It should be taken for what it is ... guessing. The media and fans will try to predict who will be contacted by which teams and who will be visiting.

For example, last year, there were many rumors flying around about linebacker Adalius Thomas. Some rumors even had him staying in Santa Clara the night free agency started. Not only was Thomas not in the Bay Area, but he never visited with the 49ers and signed with the Patriots instead.

However, Friday will likely be the day when all of the excitement begins. While rumors will continue to fly, deals are not likely to occur until close to the afternoon, once the free agents visiting have had a chance to visit with the team in Santa Clara.

49ers beat writers like Matt Maiocco and Matt Barrows will likely be on hand at the team's facility and keep fans updated on their blogs.

So for those hoping to hear some exciting news tonight, the news will likely just be rumors.
