Bill Simmons of ESPN has a "wild theory" that the San Francisco 49ers may be interested in New England Patriots quarterback Tom Brady in 2009. It hardly should even be categorized as a rumor, but feel free to take it for what it is.

The Patriots will franchise Matt Cassel in fear that Tom Brady might not make it back in time for the 2009 season. By mid-July, when it becomes clear Brady is fine, Cassel quietly will go on the market ... and, of course, the Niners will be sitting there waiting for him. As soon as Cassel becomes available, San Fran will toss the Pats a 2010 No. 1 and a 2011 No. 2, then rip up his contract and give him something like $55 million for seven years with a $24 million signing bonus. Everybody wins.
