Three of the best offensive linemen from the Football Championship Subdivision were part of the first groups of prospects to open the NFL Combine on Wednesday.

Offensive tackles Tom Compton of South Dakota, Paul Cornick of North Dakota State and Dustin Waldron of Portland State hoped to impress the 32 NFL teams which began evaluating over 325 of the nation's top college players, including 22 from the FCS, at Lucas Oil Stadium.
