Mike Tomlin shares what's impressed him most about rookie CB Joey Porter Jr.

Despite some early adversity, Pittsburgh Steelers rookie cornerback Joey Porter Jr. has impressed head coach Mike Tomlin with his commitment to adapting to the NFL game, especially considering the position he plays. 

"The cornerback position, in particular, it's probably got more of an adjustment from college to pro than any other position in the game because of the differences in the rules in terms of contact beyond five yards," Tomlin said via Jeff Hathorn of 93.7 The Fan. "So, he's doing a really good job of being cognizant of that."

Tomlin added that the transition is especially tough for Porter because of his aggressive style of play. 

"He's a line-of-scrimmage corner," Tomlin said. "Hand play has been a significant component of his game, and so that adjustment we cannot underestimate, but I appreciate his efforts in that regard, and he's being productive in the midst of it."

Porter has had his fair share of ups and downs during camp, given not one but two "Welcome to the NFL" moments by receiver George Pickens. First, Pickens ran over Porter during seven-on-sevens last week. Then, on Wednesday, Pickens made a spectacular one-handed grab over Porter before holding the ball in the rookie's face.
