CHARLOTTE -- As the first three players strolled up the path to the Carolina Panthers' practice field Wednesday, a few reporters looked down at their rosters.

Numbers 15, 12 and 10. Who are they again?

If folks who cover the team are still not familiar with Marvin McNutt, Tavarres King and De'Andre Presley, it is no surprise fans and folks outside the Carolinas are still wondering which receivers quarterback Cam Newton is going to throw to in 2014.

Sure, the Panthers brought in a familiar name when they drafted Kelvin Benjamin last month, but as promised, the lesser known guys are getting chances they never had previously.

"One of the things that we've tried to make sure is that everybody is getting a lot of reps right now," Panthers head coach Ron Rivera said after Wednesday's OTA session. "When we get to training camp, we want to make sure everybody is up to speed. We made an emphasis that we're rotating a lot of players as much as possible. Wide receiver is one of those positions."

Panthers general manager Dave Gettleman is a big believer in developing young talent, and the only way to do that is to get guys reps. That was one of the reasons Gettleman was willing to revamp his wideouts this offseason.

McNutt and King are each going into their second NFL seasons, but neither have caught a regular-season pass. Presley is a former college cornerback, turned defensive back, turned receiver. All three have a legit shot to not only make the final roster, but to make meaningful contributions this year.

Perhaps there is a Victor Cruz-like gem in there somewhere. Or maybe the receiving situation is as dire as many assume. But it certainly is still too early to know either way.

"There are guys that are catching your eye; the hard thing and the thing we have to be realistic about is we're only in shorts and helmets," Rivera said. "Once we get into pads is when you really get a feel of what they're capable of."
