SPARTANBURG, S.C. – There was a lot of noise surrounding wide receiver Kelvin Benjamin before training camp began. Was he overweight? Was he going to be able to stay healthy?

That noise has gone silent.

Instead, everyone is talking about how dominant Benjamin looks in his second training camp.

Wide receivers coach Ricky Proehl believes the questions about Benjamin's weight and the status of his hamstrings, which he pulled during organized team activities, lit a fire under the former first-round pick to silence any doubters.

"Absolutely," Proehl said. "I've only been with Kelvin for a year, but I've gotten to know him pretty well. People don't understand – he's a prideful guy. He takes a lot of pride in what he does.

"That hurt him – pulling one hamstring and then pulling the other one during OTAs. He works hard and he wants to be great."

After posting 1,008 receiving yards and a team-leading nine touchdown catches as a rookie, Benjamin arrived at training camp in tremendous physical condition, fully intent on being even better in 2015.

So far, he's right on track.

"I think it was a good experience for him, too. It was a humbling experience," Proehl said of the challenges Benjamin faced during OTAs. "He came in with a chip on his shoulder. He arrived in great shape – lost a ton of weight. He shows why he's our No.1 receiver. He's everything you want in a wideout, and I'm glad we have him."
