Key signees: Clay Belton, QB, Findlay; Terrell Sinkfield, WR, Northern Iowa; Alonzo Highsmith, LB, Arkansas.
The speedy, athletic Belton is smart and has good arm strength; he's the kind of developmental quarterback everybody wants. Sinkfield made headlines in March for running a reported 4.19-second 40-yard dash. Though that too-good-to-be-true time was almost certainly just that, Sinkfield does have good size and speed. Highsmith's greatest value is likely to be as a standout special teams player.
