Brown was elected a captain by his teammates despite the fact he's yet to play a game for the Wildcats.
"Now that's pretty special when you haven't played a game," said Cosh. "It shows he made good use of his time in developing relationships and working hard on the scout team last year. That's a place where you can go waste a year, or, you can use the time to get better. He worked hard every day and was voted a captain. I promise you, that's not just a popularity contest. You have to show something in practice."
The 6-1, 223-pound junior runs the 40-yard-dash in the low 4.5s, benches 345 and squats 545.
"He has great closing speed. He can go from 0 to 60 like a Ferrari," said Cosh of his product of Wichita East High School and transfer from the Miami Hurricane program. "He just has cat-like quickness, plus he also has a nose for the football."
Behind Brown will be the experienced team captain Alex Hrebec (5-11, 240, Sr), who has logged action in 34 K-State games and has 177 career tackles.
"Alex is just a great addition in that he has great experience and has played all three of the linebacker positions," said Cosh.
Tre Walker (6-3, 222, Soph) will get the first look at "Will" linebacker, with Jarell Childs (6-2, 217, Jr) serving as the top reserve.
Walker played in all 13 games as a true-freshman, which included a pair of starts. With his 47 tackles, Walker was named a Freshman All-American.
Childs played running back with the Wildcats in 2008 and 2009 before being move to linebacker last year when he had 53 tackles.
"Tre plays with such great spirit and enthusiasm," said Cosh. "He has that knack to find the football that you can't teach. He's gained strength, and that experience he gained last year will be a great help.
"Jerell was just learning the position last year," said Cosh. "He has great cover skills and has some flexibility to his game."
On the strong side at "SAM" linebacker are Emmanuel Lamur (6-4, 225, Sr) and Jonathan Thuman (5-11, 197, Fr).
Lamur, a team captain, played his first two seasons as a KSU safety before stepping forward to a linebacker position late last year. Lamur has 114 tackles in his KSU career, which included 68 as a sophomore and 46 more last year.
"Lamur has that great length. He can cover a lot of ground by just putting his arms out," said Cosh, who also serves as KSU's defensive coordinator. "He's like a young colt out there. He's an older guy, but yet so new at the position and is just taking everything in."
Of Truman, a redshirt-freshman, Cosh said, "He plays with great strength. He's an ex-wrestler and plays with that toughness."
Additional depth will come from Blake Slaughter (5-10, 227, Jr), who has played in 21 K-State games with 50 tackles.
