If you want the underrated guys then among my favorite seniors would be:
QB Brad Sorensen, Southern Utah (really I just have a thirst to see more of him)
RB Dennis Johnson, Arkansas
WR Aaron Mellette, Elon
DE Dion Jordan, Oregon
DE Malliciah Goodman, Clemson
DE Cornellius Carradine, Florida State
DT Cory Grissom, South Florida
LB Shayne Skov, Stanford
LB A.J. Klein, Iowa State
LB Jake Knott, Iowa State
LB Sam Barrington, South Florida
LB Kenny Tate, Maryland
CB Kayvon Webster, South Florida
CB Terry Hawthorne, Illinois
SS Shamarko Thomas, Syracuse
FS Vaughn Telemaque, Miami (FL)
Kind of a sparing list at the moment, to tell you the truth.
