These three newcomers figure to contribute right away for Wisconsin this fall.
OFFENSE -- Kraig Appleton, WR, Fr.
Wisconsin made waves on signing day by inking Appleton, who originally committed to Illinois along with teammate Terry Hawthorne. Despite some progress from the wide receivers this spring, the position remains a question mark for the Badgers, and Appleton should step in right away. He's a big target at 6-foot-4 and 190 pounds and will work his way into the rotation during preseason camp. Appleton, who was a standout track athlete in high school, can stretch the field.
DEFENSE -- J.J. Watt, DE, So.
Watt has changed schools, changed positions and completely changed his body. Wisconsin should love the end result. Needing to replace three multiyear starters on the defensive line, the Badgers will lean on Watt, who can play either position up front. Watt, who started his college career playing tight end for Central Michigan, wowed the coaches and his fellow teammates during spring practice. He's exceptionally strong and picks up coaching well.
SPECIAL TEAMS -- Montee Ball, RB, Fr.
There isn't an obvious special-teams standout among Wisconsin's incoming class, but Ball could see the field here. Head coach Bret Bielema raves about the kid, but with the running back position still loaded, Ball's best chance for playing time likely will come on return and coverage units.
