SANTA CLARA, Calif. -- As the San Francisco 49ers start their month-plus break before training camp, the top story surrounding the team during this quiet time will surely be the holdouts of tight end Vernon Davis and guard Alex Boone.Both became official holdouts when they missed the three-day mandatory minicamp that ended Thursday.Don't expect much news for the next few weeks unless either player unexpectedly signs a new deal. I'd be surprised if anything happens quickly with either player who are both signed through the 2015 season.
