Josh McDaniels would prefer to join the San Francisco 49ers if he decides to leave the New England Patriots, according to a source.

McDaniels will interview with the 49ers, Los Angeles Rams and Jacksonville Jaguars on Saturday near the Patriots' facility. 

The 49ers are the only team also with a general manager opening. That vacancy combined with Jed York's commitment to patiently rebuilding and their status as a marquee franchise makes them more attractive to McDaniels than Los Angeles and Jacksonville.

McDaniels, who has served as New England’s offensive coordinator and quarterbacks coach since 2012.

ESPN analyst and former NFL executive Louis Riddick, who reportedly will interview with the 49ers next week, has been an avid fan of McDaniels on social media. Riddick and McDaniels also have strong ties to New England head coach Bill Belichick.
