So far, his first NFL playbook and the complexities of the Giants’ defense have not led to any big surprises for Deonte Banks.

The first-round draft pick out of Maryland will be given every opportunity this summer to win a starting cornerback role.

He must stay on the field, stay engaged and show he is capable of handling the success, and especially the adversity, that is sure to be part of his rookie experience.

The Giants liked plenty about Banks and they were impressed with the way he aced the pre-draft meetings they had with him, as far as being able to understand and explain the techniques he was presented with on the board.

“First, I take notes,’’ Banks said Friday of how he takes on the mental part of his indoctrination. “I take notes on my stuff and learn what I can learn from my position, and then I try to see the bigger picture, and see what everybody else is doing. Also, ask vets what they’d do or how they’d look at this or things like that.’’

It is clear that Banks, from a physical standpoint, looks like the real deal.

At 6-foot-2 and 200 pounds, he can stand and run with any of the receivers in camp. He said the main adjustment from college to the NFL thus far is “probably how up-tempo it is and the speed of it.’’

Banks is a talker on the field, but is not a proponent of saying what he is going to do. He does not lack confidence, though.

“I feel like I can challenge anything,’’ he said. “I can always hold my own.’’

Banks was heavily involved in his third practice of camp.

He was beaten by a step on a deep ball to receiver Darius Slayton but came back with tight coverage on tight end Darren Waller, springing from one side of the field to the other to make the pass breakup.

It was Ben Bredeson’s turn to work at center with the starting offense. Josh Ezeudu was the starting left guard.

After two morning practices, the starting time on Friday was 5 p.m., giving the players extra time for their bodies to recover. It was 93 degrees as practice got underway and there were several water break stoppages in the intense heat. During the walk-through periods, players were allowed to take off their helmets.

“Just to let the heat get out a little bit,’’ head coach Brian Daboll said. “Try to manage them the best we can.’’

The session was supposed to end at 7 p.m., but it ended 25 minutes early.

After opening camp with three consecutive practices, the players will be off on Saturday. They will return to the field on Sunday, with the first day in pads in the ramp-up period set for Tuesday.
