Freshman Ricardo Allen has started every game in his first season for Purdue, and sophomore Josh Johnson joined Allen in the starting lineup in Week 3.
They've been consistently productive in their first years as starters.
Allen leads the team with three interceptions, two of which he's returned for touchdowns, and is fifth on the team in tackles (65). Johnson has 50 tackles. three forced fumbles and has an interception.
"Those guys are really good football players," coach Danny Hope said. "They're very active. They're really quick. It's exciting to watch the films.
"I don't know there's a better corner in the league than Ricardo Allen right now, and Josh Johnson is one of the better players on our football team. He's really grown up. He's always been a good player, a good prospect, but he's really matured and grown up the latter half of the season."
