. >> maureen naylor live tonight in santa clara. word of miller's arrest comes as the 49ers deal with big changes to their roster. today two key players left the team, and there could be more changes on the way. >>> one big news story after another, really all off-season long. i'd say probably the fastest fall from grace i've ever seen in bay area sports. for the most part, it's cyclical. teams go through bad times on the field, but for the 49ers they've gone from the super bowl just two years ago to mediocre on the field, and perceived chaos. aside from another the arrest of a player a few days ago, two of the team's dynamic leaders, apparently ready to sign with philadelphia over the weekend, but he's had second thoughts and may actually wind up with indianapolis. either way, gore is out the door. earlier today, news leaked out that patrick willis will announce his retirement tomorrow at the age of 30, citing constant foot problems and a spiritual awakening. not to mention michael crabtree is set to leave as a free agent. colin ka
