Auburn defensive tackle Sen'derrick Marks says he'll declare for the 2009 draft. It's not obvious where he will fall come draft day. He totalled just 3 sacks in his junior year and is a 4-3 three technique pass rusher. The Seahawks could really do with finding a big body to fill up some space which Marks isn't. He's appeared on various mocks in the top two rounds but more realistically he's a second day pick.
