Mel Kiper's top 5 seniors by position

A big story here: I moved Tim Tebow back to No. 2 among senior quarterbacks. (He had fallen in recent weeks.) Another big story: the emergence of small-school players. Tony Washington from Abilene Christian debuts at No. 4 among my senior offensive tackles; Vladimir Ducasse of UMass starts off as my No. 3 senior offensive guard; and John Gregory from Tusculum, the Division II's special-teams player of the year, shows up at No. 5 among my senior punters. As always, these positional rankings and the Big Board don't necessarily reflect recently determined 2010 NFL draft order. The first mock draft -- which obviously will reflect that -- will show up on Jan. 20 right here.
