IRVING, Texas -- Retired Carter High coach Allen Wilson stopped by Valley Ranch to check on a couple of his former players.

Outside linebacker Adrian Hamilton and cornerback Isaac Madison are undrafted free agents who have legitimate chances to compete for a spot on the 53-man roster. That comes as no surprise to Wilson, who coached several NFL players throughout his career, including a couple that played with Hamilton and Madison at the south Dallas high school: San Francisco 49ers receiver Michael Crabtree and Minnesota Vikings offensive lineman DeMarcus Love.

“It ain’t got nothing to do with coaching,” Wilson said while watching Thursday’s rookie camp practice. “When they were born, they had it. I didn’t make Isaac fast. I didn’t make Adrian look like he looks. Their parents gave them the genes. We were just at the right place and had the opportunity to coach them.”

Hamilton had a twisted road from Carter to Valley Ranch, originally signing with Oklahoma State and spending time at a junior college, Texas Tech and a community college before breaking Indianapolis Colts defensive end Robert Mathis’ SWAC season sacks record at Prairie View A&M.

Madison had some injury-related bumps in the road during his time at Arkansas.

Here are the scouting reports on the Carter products from their high school coach, who visited with his former players and Dallas defensive coordinator Rob Ryan after practice.

Wilson on Hamilton: “It’s just one of those natural things to rush around that edge, rip under a guy or over a guy and go get the passer. Then he had enough speed that when the quarterback is flushed, he can just chase him down. Those are the guys that make a difference. And he’s tough, don’t back down from a challenge.”

Wilson on Madison: “He had world-class speed in high school, and then he had cover ability. He could flip his hips and run. He could change direction. He can do all those things. This is one of those special kids. He’s just go to stay with it. He’s just had some injury problems that have cost him some days, but outside of that, he’s another one of those guys that’s a great kid, came to work every day and had the tools it takes to play at the Division I level and at this level. When you look at a corner, the first thing you think of is speed. Can this guy run? That’s what he can do. … He’s a tough kid. He’ll come up and hit you. He ain’t one of those guys that shy away.”
