"I transferred this semester to play ball down here at Louisville," the 5-foot-10, 175-pound Sadler told InsideTheVille.com.
The Cardinals recruited Sadler out of high school but did not offer. Sadler signed with Western Michigan in 2008, and held several other Mid-American Conference offers. He will have three years of remaining eligibility.
"He can run," Colerain coach Tom Bolen said. "He's probably a 4.4. or 4.5 kid. He (was) a three year starter for us. He's not a real big kid – he's probably 5'9 or 5'10 and about 180 pounds. But he's a kid that plays much bigger. He (was) our field corner – kind of our lockdown corner. He's a real physical kid for his size and he plays bigger than he is. He likes to hit and he likes contact."
At Colerain High School, Sadler was ranked No. 60 overall in the state of Ohio by Scout.com. Sadler registered 40 tackles with 14 pass break ups and two interceptions as a senior.
