New-look offensive line among big 49ers changes

Beeler sees the similarities — besides the notable artwork — in Harbaugh's transition to the 49ers and his Stanford days. The difference now is the larger stage — and greater expectations.

"I think we'll click in pretty quickly," Beeler said. "I think that's the thing coach Harbaugh was so good at doing at Stanford, fostering an environment in training camp that brought people together. It's hard to articulate exactly what that is or how he's able to do it, but I see echoes of that here."

Notes: The 49ers signed free agent fullback Jack Corcoran to a three-year deal. He was an undrafted free agent with the Houston Texans in 2010. ... 49ers cornerback Reggie Smith confirmed the team voted unanimously to recertify the players' union.
