The Tampa Bay Lightning might not make a serious offer for Brad Richards. Although the Lightning were among the initial candidates for Richards' services, their cap situation might get in the way. They still haven't signed restricted free agent Steven Stamkos, and it's hard for them to gauge how much room they have before that happens. In addition, they need to account for the fact that Steve Downie and Victor Hedman will become restricted free agents in 2012. It would be interesting to see Richards back in a Lightning uniform, but it isn't likely to happen.
