Smith was entering the final season of the six-year, $45 million contract he signed in 2008. Expect this extension to kill two birds with one stone; soften his 2013 cap hit and keep Smith in town through his age-36 season. Smith's 2012 late-year effectiveness was sapped by a triceps tear, but he's still one of the game's best 3-4 ends. He graded out as Pro Football Focus' No. 1 player at the position in 2011, 2010, and 2009.

With Michael Crabtree (Achilles') out, Anquan Boldin only capable of playing the slot and a host of question marks battling for the X receiver spot, we knew Davis was going to have a big role in the passing game. By learning the wide receiver positions, he'll have more scheme versatility come Sundays. Davis can line up as an in-line tight end, a move tight end, in the slot and out wide. The 49ers' dominant offensive line frees him from too many blocking responsibilities. They're going to be a run-heavy team, but when they pass we expect Davis to be featured heavily.

"There are enough people around the league that believe Matt Cassel is good enough to challenge Ponder," stated Schefter, adding that Cassel "could unseat Ponder at some point this season." Although Schefter confirmed Ponder won't lose his job before Week 1, he called it a "situation that bears watching." Ponder endured a brutal nine-game stretch last season (Weeks 7-16) where he completed 140-of-245 passes (57.1 percent) for just 1,267 yards (5.17 YPA), and a 7:8 TD-to-INT ratio with two lost fumbles. Ponder was serviceable to solid (67.2 percent, 7.01 YPA, 11:4) in his other seven starts.

Bishop is meeting with the Vikings on Tuesday. By arranging a visit with another suitor, his agent exerts some leverage over Minnesota. If they want him to help fill their gaping need at inside linebacker, they better get a deal done before he leaves town. Bishop would provide the Chiefs with a significant upgrade over Akeem Jordan at the inside 'backer spot next to Derrick Johnson.
