Every player who makes the transition from college to the NFL will have to make adjustments to their game.
It's not different than the jump from high school to college - maybe just more intense.
Even players who come from major college programs have some period of adjustment. And Pittsburgh Steelers first-round draft pick and defensive tackle Derrick Harmon is no different.
As the team wrapped up mandatory minicamp on Thursday, Harmon still has yet to see true NFL action, but he already knows what his biggest adjustment will be while making the jump to the NFL.
"Biggest difference for me is really just learning the speed of the game, " Harmon told reporters. "Hardest thing, the speed of the game is way different than college."
The Steelers will now break for six weeks and can rest before training camp starts. But Harmon has other plans. The Detroit native plans on working out in Dallas this summer in anticipation of training camp in Latrobe.
"They mostly said it was going to be hot," Harmon said of training camp." That's pretty much it. They said it was gonna be hot. So I'm ready for it. Being in Texas heat, just getting ready for that."
Head coach Mike Tomlin is excited to have Harmon on board and thinks he "has Steeler DNA."
"He has Steeler DNA for us, man. It starts inside and upfront, and this is a guy that's capable of dominating that space versus the run and the pass," Tomlin said. "And so we're really excited about having him. We weren't interested in considering trading away from him and really excited about getting him in here and getting started."
