Martz: 'So many questions' for 49ers' offense

Posted by ESPN.com's Mike Sando

Mike Martz's recent chat for NFL.com featured a few starting points for conversation. Asked whether the 49ers' Vernon Davis could catch 80 passes, Martz replied: "He can, but there are so many other questions to answer in that offense before you try to get anybody 80 passes."

Quarterback is clearly one of those questions in Martz's mind. Asked to choose between Shaun Hill and Alex Smith last offseason, Martz chose J.T. O'Sullivan.
