Robby Anderson came to Jets training camp a year ago as an unknown.

Anderson, an undrafted free agent out of Temple, was buried on the depth chart and a long shot to make the roster. But he had an outstanding camp and made so many plays in the preseason games the Jets had to keep him.

The move paid off. Anderson became a key piece for the Jets after injuries to Eric Decker and Jalin Marshall early in the season. He emerged as a deep threat and finished his rookie year with 42 catches for 587 yards and two touchdowns.

Now, he wants to do more.

“I’ve still got a lot to prove,” Anderson said Tuesday. “I know the whole world is doubting me. That’s how I look at life. I’ve always felt like I’ve always been doubted. I wake up and I walk around with a chip on my shoulder on a daily basis.”

The doubts this year are about whether Anderson can go from being a complementary wideout to being a reliable starter. The Jets cut Brandon Marshall and Decker this offseason, leaving Quincy Enunwa and Anderson as their top two receivers.

“I’m excited,” Anderson said. “I feel like I’m in a different place coming in this year. I’m working to be a starter. Last year, I was working just to make the roster.”

Anderson spent this offseason trying to add weight to his skinny frame. The 6-foot-3 Anderson said he is up to 180 pounds after playing last year around 170. He said his goal is to be 185 by the time the season starts. He is not concerned about losing any speed because of where he is adding the weight.

“I know I’m gaining a lot of weight in my legs,” Anderson said. “My legs are way bigger than they were last year. I feel more explosive.”

His teammates have noticed a difference in Anderson already.

“He’s just a stud,” said quarterback Bryce Petty, who clicked with Anderson last year. “He’s learned. He’s grown. He might be faster. Honestly, he might be faster. He’s taking things that [offensive coordinator John] Morton is telling him in the film room and in the meetings, and he’s taking it to the field. It’s showing up. He caught a little 3-yard route, and I thought he took it to the house. It might have been close. Just his burst, it’s exceptional.”

Anderson did not have a seamless offseason. He was arrested in May for allegedly pushing a police officer at a concert. The case is pending, and Anderson cannot comment on it.

On the field, the Jets are counting on Anderson. The offense lacks a lot of explosive players. Anderson could be that guy. He has blazing speed that was on display many times last year, but he and quarterback Ryan Fitzpatrick never seemed to be on the same page, and Fitzpatrick missed him several times. Anderson played better with Petty at quarterback. If Anderson can provide the Jets with a deep threat, that could open up some things underneath for other receivers, the tight ends and the running backs.

Anderson is just 24 years old, but he is being asked to grow up fast. The Jets’ receivers room is so young you might expect to see some toys on the floor. But Anderson said people should not overlook them.

“We’re hungry,” Anderson said. “I think we’ve got some good momentum. I feel like we had an extremely good practice as a group. I think the key is consistency. We’ve just got to continue to be consistent, keep working hard, taking the meetings onto the field and keep taking steps to greatness.”

As for Anderson, he said his goal “is to contribute to my team getting to the Super Bowl.”

No one outside the Jets organization thinks the team can do that.

“Everybody knows that,” Anderson said. “That’s not a secret.”

Does that motivate him?

“Definitely.”
