He's 6'6", 302 lbs. He might start this year if he has a good training camp. I'm not big on our current starting OG Jake Scott. Scott's play against Pittsburgh was a big reason why we lost that game. He and Ryan Lija did oh-lays! to guys like Porter and Farrior.
With Toudouze, this might be an upgrade. He has a lot of skill, and o-line coach Howard Mudd has done a lot more with a lot less.
NFL.com has a profile of Toudouze.
