Depends on what your deffition of "big name" is. If Keyshawn in 06 is the standard then I would say the last one was 2012 with Tolbert. Hurney doesn't usually go after the best at a position but he has signed guys like Tolbert, Shockey, Lucas, Wahle, Kemoeatu, D Lewis, and Brayton. They're not HOFers but solid players and usually are regarded as "top 100" players available.
Read Ivans post...#15. That pretty much sums it up.
