*Giants WR Brandon Marshall is yet to make a big impact on his new team: *

EAST RUTHERFORD, N.J. – Brandon Marshall wants to do more.

The six-time Pro Bowl wide receiver, who signed with the team on March 8, concedes he hasn't made the positive impact he expected to have on the offense in his first season with the Giants.

Through four games, Marshall has been targeted 30 times and caught 16 passes for 139 yards, an 8.7-yard average that is about four yards less than his career mark entering the season. He has not scored a touchdown, and has had some high-profile and critical drops, notably on a long third-down pass against Detroit on Sept. 18.

"I haven't played the way I've wanted to play," Marshall said. "I hold myself to a high standard. The guys around here hold me to a high standard. There's high expectations on all of us and looking at myself in the mirror, I want to pick up my play and I'll do that. But I'm not going to waste too much time thinking about the past. If I do that, then the future is going to be really ugly."

The Giants' present isn't particularly pretty right now. When they host the Los Angeles Chargers on Sunday, it will be a clash of 0-4 teams. Marshall is one of many players that can help the Giants end their losing streak by raising his level of play.

He caught just one pass in each of the first two games. In the opener in Dallas, his lone catch was a 10-yarder on the game's final play. That kept alive a streak that has seen him catch at least one pass – and usually several more – in 163 consecutive games.

Marshall had eight catches for 66 yards in Philadelphia on Sept. 24, and six for 46 yards last Sunday at Tampa Bay. But he doesn't look as comfortable, nor has he been as dominant, as expected.

"I think catching is confidence," coach Ben McAdoo said. "He seems to be double catching a little bit, and we just need to get through a clean game with him. He's been catching it well in practice, we need to carry it over to game day. And that's a part of the game for receivers."

Why is a veteran with 957 career catches, the 16th-highest total in history, having difficulty finding a comfort zone?

"I think it's a new offense," McAdoo said. "He's doing a lot of learning. He's still doing a lot of learning. Playing with a different quarterback. He hasn't caught the ball cleanly in games."

Marshall is not particularly interested in discussing how either he or the team arrived at this unexpected juncture.

"I respect you guys and your job, but I moved on to Los Angeles, we've moved on to Los Angeles," he said. "It sucks to be in this position. It's not the best position, but I've got to play football. So I don't want to spend all my time thinking about what we did in Week 1, Week 2, Week 3, Week 4. If we do that, then we're not going to get out of this hole that we dug.

"So I'm moving on. I respectfully decline any questions about our culture, any questions about our losing streak. My play – my play hasn't been where I want it to be. I need to pick it up. But I'm not going to waste too much time talking about a losing environment. I came here to win, so hopefully that answers any questions you guys may have had outside of football."

Marshall is accustomed to dealing with adversity and disappointment. He has played in 171 games for five teams in 13 seasons, and has never participated in a postseason game. Marshall believed coming to the Giants and catching passes from Eli Manning gave him his best chance to finally make the playoffs. By opening the season with four losses, they have a challenging climb ahead of them.

"Football makes you tough, football helps build your character," Marshall said. "You come in a boy and you leave a man. Being 0-4, it stinks, but there's worse things in life. And have the guys in this room have been through (what I have). This is our job, we're paid to do a job and we've got to get it done. We just need to find a win. We find a win, the environment will be so much better."

*After four successes, Aldrick Rosas had the first missed field goal attempt of his career, a 43-yarder early in the fourth quarter. Had he made it, the Giants would have led, 20-16.

"It's my job to extend the lead when we get the chance to," Rosas said. Asked how he handled his first miss, Rosas said, "The kicker mentality is just one for one. We hit the reset button after every kick. You just go out there and you just keep building on your routine and keep progressing, and keep doing what you've been doing."
