Las Vegas Raiders edge rusher Clelin Ferrell is hell-bent on reforming his body in preparation for his second NFL season.

The 23-year-old Clemson University product, the fourth overall pick of last year's draft by the Raiders, Ferrell has reportedly gained over a dozen pounds of muscle in the offseason in order to bulk up and turn into a sack machine.

Per Vic Tafur in The Athletic, via ProFootballTalk:

“He’s lean and mean and running pretty good,” trainer Mark Hall. “We had a really good offseason and I know he can’t wait to get to Las Vegas and put that product on the field.”

“Last year was more of an introduction to Cle,” Hall said. “Then last season, I noticed some deficiencies in Cle’s game and the Raiders played him inside some, too. So he needed to put on some more pounds, especially in his lower body, and we polished up his pass-rush game.

“We also wanted to give him a better understanding of what offensive linemen are presenting to him, and how to finish against them. Clean his game up, . . . speed, agility, movement.”

Ferrell recorded 4.5 sacks in his debut professional season with the Raiders in 2019. He appeared in 15 games, combined for 38 tackles, eight tackles for losses, and eight quarterback hits, per Pro Football Reference.

The Raiders last season total tied for the 18th-most sacks against opponents. For Ferrell, transforming his athletic body into a pass-rushing machine could truly move Las Vegas' defense in the right direction and pressure opposing quarterbacks.
