The 49ers go with an all defense press conference today starting at 11:30am PT. Today will feature offensive coordinator Greg Roman, quarterback Alex Smith and offensive guard Mike Iupati.

I don't think I recall seeing Iupati speak at a press conference since he was first introduced after the 2010 NFL Draft. I am curious to see if he gets any questions about his thoughts on Alex Boone's adjustment to guard. I would think he could provide some valuable insight about the development of another guard. Of course, I wouldn't expect any critiques of Boone's work, but who knows.

I've embedded the live stream after the jump. If you have any problems, check out the 49ers.com live stream.
