"There's always that first hit that rings you, so you can get back into hitting," McKelvey said. "But, coming back, learning how to fit things ... I'm not that big of a linebacker, but trying to beat offensive linemen much bigger than you, you have to learn the technique. Being rusty, they can get up on you really quick."
McKelvey is happy to have Fuller guiding him this season. He said the former University of Tennessee at Chattanooga defensive coordinator makes learning the position much easier, breaking down plays to their essence and making sure every linebacker understands what he's supposed to do.
McKelvey wants to be 100 percent both physically and mentally to make a mark in new defensive coordinator Chuck Heater's scheme.
He also wants to try to eclipse the work of his older brother, a 2011 all-Conference USA first team safety who make the Baltimore Ravens as an undrafted free agent and earned a Super Bowl ring in January.
McKelvey appreciates the standard Brown set both for him and their brother, University of Kentucky junior linebacker Kory Brown. McKelvey does, however, feel he's passed Omar Brown in one category.
While his older brother may have the lead on him in on-the-field success, McKelvey has declared his domination of Omar Brown in the John Madden football video game. Brown has claimed McKelvey is dominating him on the game console, but McKelvey has a different opinion.
"He's a person that's in denial," McKelvey said with a laugh and a smile. "I'm just that much better than him at Madden. And when I win, it's not just a win. It's a blowout."
Fuller said that, if McKelvey keeps working, he could reach what his older brother has done at Marshall as well.
"Everything I hear about (Brown), it seems they're cut from the same cloth - a really good human being, loves Marshall and loves the game," Fuller said.
"Evan's ready to make his own mark."
