The Giants already know what it is like having to deal with Robert Griffin III and have conferred with college coaches to help them prepare for the high-octane offense new head coach Chip Kelly is bringing to the Eagles. There’s a need for speed in the NFC East and there’s a linebacker available in the NFL Draft who can provide it.

“I definitely do think I can catch them,’’ Alec Ogletree told The Post Tuesday. “I feel very comfortable in my ability to play and chase people down or hit them square in the face. I feel like I’m very versatile. I feel like there’s a need for guys like me and I think I’m one of the best at doing that.’’

There’s a glaring need for guys such as Ogletree, who is leaving Georgia after his junior year and might have the most upside of any linebacker in the draft. The Giants have the 19th overall pick and a 28-year history of not taking a linebacker in the first round, but they also have a roster devoid of a true playmaker at the position, plus the recent memory and continuing threat of RG3 dancing through their defense.

Would the Giants take Notre Dame’s Manti Te’o? He’s considered a top inside linebacker but he comes with all that baggage from his bizarre imaginary girlfriend controversy and might not be able to hold up as a true NFL man in the middle. Ogletree, on the other hand, is a huge talent but taking him at No. 19 is far from a sure thing.

One reason Ogletree is a bit of a risk is because of his off-the-field issues. He was suspended for the first game of his freshman season after he was arrested and charged with theft for stealing the motorcycle helmet of a Georgia track athlete. He was suspended for the first four games of his junior year for violating the school’s drug policy. And then, showing incredible immaturity, he was arrested this past January in Arizona — less than two weeks before the NFL Scouting Combine — for driving under the influence. No doubt, many NFL teams attached a red flag label to his draft status and the first question in many interviews probed into his many off-the-field problems.

“All I can do is just be honest with them and just hopefully move forward from it and let them make their own decision,’’ Ogletree said. “Do I think I’m a risk? No I don’t think I’m a risk.’’

The Giants have taken risks before — Ahmad Bradshaw had to spend time in jail early in his career because of arrests while in college — and usually are confident their veteran leadership can help keep youngsters in line.

There’s a boom-or-bust aura hovering over Ogletree and not only because of his rap sheet. Last week, NFL Network draft guru Mike Mayock said he was “scared to death about Ogletree, both for on and off-the-field issues.’’
