Deep tackle class leads linemen

There is a chance no offensive tackle will be taken in the top 10 for the first time since the 2005 draft, but USC's Tyron Smith is a physical specimen who is expected to shine this week, and he could move into the top-10 discussion if he lives up to expectations. Smith is raw, though, and that could keep him out of the top 10.

However, this year's class reminds us a bit of 2008, when Jake Long went No. 1 overall and 21 other offensive tackles were drafted. The 2011 class is just as deep, with 23 players currently carrying draftable grades.
