Are the picks coming for Chris Cook?

SANTA CLARA, Calif. -- If Chris Cook keeps this up, he may have something for his mantle very soon.

When the San Francisco 49ers signed Cook this offseason, the book on him was he had poor play-making ability. The reason? The former second-round pick has exactly zero interceptions in four NFL seasons.

However, if his first training camp with the 49ers is any indication that may change. Cook has shown a flare for the ball in camp and he had a big day in front of about 10,000 fans in the 49ers' first practice at Levi's Stadium on Monday.

Cook picked off two passes, including a spectacular diving grab in the end zone. Cook said getting to the ball has definitely been an emphasis since signing with the 49ers.

"I focused on that mainly in the offseason and I spent a lot of time catching balls and having balls thrown at me, turning my back, then turning to look at the ball," Cook said. "I spent a lot of time doing that in the offseason, so I think I definitely improved."

Cook, a big, strong cornerback, will likely play often in the 49ers' rotation this season.
