I'm not sure, I think Young, because he goes way back with Jeff Fisher, and I think he'd fit well into the offense. They better draft O-Line as well, he has to stay upright to be successful to any degree. McNair has been hurt off and on the last few years, and it was because of the lack of skill on the line.
Could go either way though, I look for Young to go #3 overall, and Leinart at #4.
