Kiper's top five players by position

We're now less than a month from the first night of the NFL draft -- April 22, a Thursday -- and the list below, of declared players, is shifting a bit. Jermaine Gresham of the Oklahoma Sooners had been the No. 1 TE on these lists for a while, but Aaron Hernandez of the Florida Gators jumps him this week.

Donald Butler of the Washington Huskies debuts at No. 3 on the ILB list, wiping Florida's Brandon Spikes from the list entirely.

The next editions of this list -- March 31, April 7, April 14 and April 21 -- should see a great deal of change, so keep coming back.
