"For me having played in a zone blocking scheme, whether it’s full pads or no pads, I know what it should look like," Griffith said. "And what I saw (Thursday) night showed me there’s no question that they are on the right track. Are they where want to be ultimately? Maybe not at this point in the season. But I think what helps them is the fact they get to go against (Adrian) Clayborn every day. (Karl) Klug every day. Christian Ballard. When you get to practice against these guys on a consistent basis, you’re going to get a whole lot better. Because you’re not going to see many guys that are better. Arguably you won’t as a unit. I think that really speeds up the progress of this offensive line." Howard Griffith on Iowa's practice. Full story at the Doc's Office.
