Well for one Campbell is a 3 time placer, 2nd in 2007 at 112, 3rd at 119 in 2008, and 2nd at 125 last year. Wildin went 0-4 at the state tournament before last year's 2nd place finish at 130.

Wildin has also lost twice to McMichael who is ranked below him.

Not to mention that Wildin went 0-2 in the same kids bracket that Campbell took 3rd place in last year for 16 and under 135 lbs. Campbell also beat Nick Hockett of Cherryvale at the same tournament 3-2, while Wildin was pinned by Hockett. Campbell also beat Travis Reinhart of Derby 3-1, while Wildin lost to Reinhart 9-5.

I hope that answers your question of why Wildin is behind Campbell in the rankings.
