"It sucks," Cromartie told the New York Daily News, just before the deal officially went down.
On Thursday, addressing a full contingent of reporters for the first time since the April 21 trade, Cromartie sounded more resigned to the move.
"You just gotta move forward. You can't pout about it," Cromartie said. "It's a business. I think my job here is just to make sure, for one, that I'm ready to go out and play and make sure that the younger guys are ready to come out and play. That's the kind of role I'm trying to take on, and make sure guys are doing what they're supposed to do."
The Jets felt comfortable dealing Revis in part because Cromartie performed so well as the team's No. 1 corner after Revis was hurt early last season.
"I just go out and play football," Cromartie said. "If that's how they felt, that's how they felt."
Cromartie had 10 interceptions in 2007 as a member of the San Diego Chargers. But he said he felt last season was even better, because of his consistency.
"I think I can maintain the consistency," Cromartie said. "That's the goal."
As for who will be playing opposite him, the leading candidate is rookie Dee Milliner, drafted with the ninth overall pick last month out of Alabama.
"He's a smart kid," Cromartie said. "I think Dee is gonna come in and help us out a lot. Just from watching the film on him, he's a physical-type guy to come up and will support the run. That's something that's gonna help out big for us. We're not looking for him to fill anybody's shoes. He's Dee Millner and he's gotta be himself."
Cromartie also talked up Kyle Wilson, the team's first-round draft pick in 2010, who started 15 games last season.
"I think he's gonna take a big step this year. I honestly believe that," Cromartie said. "He's been working hard this offseason, both of us have. I think by us pushing each other, going out and making sure we're competing, it's gonna bring the more competitive side out of him once we're on the football field. ... I think it's gonna be his best year."
