Burney carries the highest grade per ESPN.com of players undrafted. I agree with Burney, Herzlich, Tolliver, and Saunders.

Also would take a look at the following:

Cedric Thornton, DT, Southern Arkansas
Ian Williams, DT, Notre Dame
Noel Devine, RB, West Virginia
DeAndre McDaniel, S, Clemson
Jeron Johnson, S, Boise St
Garrett Chisolm, OT, South Carolina
