PITTSBURGH -- How happy was Ben Roethlisberger that the Steelers drafted a tall wide receiver?

He waited all of 10 minutes after the Steelers selected Clemson’s Martavis Bryant in the fourth round of the draft before calling one of the newest additions to the offense.

That Roethlisberger called so soon even caught the 6-foot-4, 212-pound Bryant a little off guard.

"Yeah, I was [surprised] to be honest with you but it was a good experience for me," Bryant said Friday after the first practice of Steelers’ rookie minicamp. "He asked me when I was coming out here and I told him I report Monday."

Two days later Bryant was among those working with Roethlisberger at Steelers’ headquarters.

Nothing better encapsulates the whirlwind the Steelers' newest draft picks have experienced in the last week than Bryant receiving a call from Roethlisberger and catching passes from the franchise quarterback less than 48 hours later.

Everything continued to move at warp speed for the rookies as they practiced for the first time this morning. They will also drill later this afternoon.

New city. New team. New system.

All of it can be overwhelming, especially when the rookies have had less than a week to learn a new offense or defense before practicing under the watchful eyes of their new coaches.

“So far it’s been a wild experience with all the interviews, all the testing and learning the plays,” said mammoth defensive tackle Dan McCullers, a sixth-round pick. “It's been tough, it's been crazy but I'm slowly getting used to it. Hopefully I'm going to progress and get better every day."

Bryant agreed.

"I'm not trying to rush because when you rush you mess up so I'm just taking it day by day," Bryant said. "This is a new start for me and I want to make a great impression. I just want to come out and work hard and get better every day."
