Ray Allen announced his decision to leave the Boston Celtics and sign with the Miami Heat on Friday, July 6, 2012.
The announcement sure did cause a stir.
It's only July 16, 2012. The NBA season won't start for almost three-and-a-half months.
Over that time, there are sure to be many predictions about how good the Heat will be with Ray Allen, how terrible the Boston Celtics will be without Ray Allen and everything in between.
The Ray Allen signing could easily end up as a great summer story, without a lot of length to it.
That's how free agency works sometimes. Big-name additions don't pan out; other transactions float under the radar and end up having a tremendous impact.
There are no guarantees.
There have been a lot of free agents who have signed big deals, either in financial size or potential impact on the teams they've joined or left.
Some will definitely make an impact, but others won't live up to the hype that surrounds the summer free-agent news.
