MADISON, Wis. (AP) -- Senior safety Jay Valai has been a starter for three years at Wisconsin, and at first glance, there's not a lot that jumps out.
He's only 5-foot-9 and has just two interceptions over 47 games. His career has been marred by injuries, illness and a one-time reputation of being a dirty player.
Through it all, Valai has emerged as one of the leaders on Wisconsin's defense and helped bolster a secondary that had struggled in his first three years.
That's why Valai understands the underdog TCU's mentality. The 12-0 Horned Frogs, ranked No. 3, face the fourth-ranked Badgers (11-1) in the Rose Bowl on Jan. 1.
