Interesting about Raines -- he's listed as a senior, but he didn't play in 2009 so I figure he should have another year. That would be a boost to the line.
I think Preble will end up as your starting RT. He's a beast, as is Goodwin. I've got high expectations for those two and Intemann (who's supposed to be a bit more raw but has good potential).
I believe someone said that Ford would end up playing a lot next year despite his lack of time this season. And while Bolling has yet to contribute, he was a pretty big-time recruit.
Also 2012 TE recruit Zach Gordon should play as a true frosh and is supposed to be a pretty good blocker.
