Linemen under the microscope in Blacksburg 

October, 29, 2009
When North Carolina visits Virginia Tech on Thursday night (7:30 ET, ESPN), six notable NFL prospects will take the field. Here's what we're looking for from each:

North Carolina DT Marvin Austin (6-2.5, 303); Scouts Inc. grade: 92 -- Austin did a good job last week of clogging the middle against Florida State's undersized offensive line, but he faces a much tougher test this week. Virginia Tech's interior offensive line is at its best driving defenders off the ball, and this shapes up as a strength-on-strength matchup. Austin is better against the run than as a pass-rusher and could have success against Hokies G Sergio Render, who does not use his hands as well as Austin. We also want to see how Austin holds up against the fair amount of double-team blocks we expect Virginia Tech to throw at him.
