Before Carolina quarterback Cam Newton began goal line drills with his receivers, he glanced to his left. There Kelvin Benjamin stood side-by-side with Devin Funchess. It must have been a soothing sight for Newton. The Panthers hope it’ll be a scary one for opposing defensive backs for many years to come.Benjamin, who destroyed Panthers’ rookie receiving records in 2014, is just 24. Funchess, Carolina’s second-round pick, turned 21 last month.“He’s a young player, he’s still learning. I’m still young, I’m still learning. We’re very big receivers for Cam,” Benjamin said Thursday.At 6-foot-5, Benjamin is just slightly taller than Funchess. Some NFL scouts pegged the rookie as a potential tight end, but Benjamin has a body better suited for that wild idea. He’s wider and more muscular with a bigger catch radius. Funchess is more fluid and has a certain finesse when he makes a catch. Perhaps too much.“He’s big, but we played at different schools, so we were taught different things. He can learn from me, though,” Benjamin said. “I’m trying to make him more physical so he can be a big, physical receiver. You know, use his size.”Benjamin, who missed the first seven OTAs with a strained hamstring, was limited after returning Tuesday. He expects to do more during next week’s minicamp when we may get an even clearer view of the Panthers’ future.“It’s coming along good. We’re still taking our time with it; we don’t want to rush,” Benjamin said. “We’re getting there. Hopefully next week.”
