I know this has been talked about; in fact, I think Ed mentioned it a bit ago but the Giants have the best trio of receivers in the league, hands down.
Steve Smith, even as a rookie, showed that he could be Eli's favorite target. I'm sure you all can remember that critical final drive in Super Bowl XLII when the Giants faced a 3rd and 11 at around the Patriots' 30 yard line. He showed hands, guts, smarts and quickness to be able to avoid Meriweathers' hit long enough to get to the marker and get out of bounds. Since then, Plaxico shot himself, went to prison, and Hakeem Nicks has emerged.
Hakeem Nicks showed flashes his rookie season towards the latter end when he merited some playing time. He showed hands, speed and an ability to fight through arm tackles. He demonstrated good down field vision and used his blockers well. He was often able to turn a simple swing pass into a 20, 40, or 60 yard reception. As this breakout season demonstrates, it was no fluke. He's tough to contain in single coverage and, depending on the matchup, he's a sure thing a lot of the time.
Manningham is very capable of making big plays and even though he isn't a huge part of this offense, it doesn't mean he couldn't be. He's relatively smaller than the other two and has a harder time fighting off press coverage; however, with Nicks and Smith receiving every play double coverage, it leaves a swift and agile receiver man to man on a 3rd CB or vulnerable safety at all times. The guy's going to find some plays to be made and he's got the ability to convert.
Here's the kicker...
In the beginning of the season, coverage was always rolling towards Steve Smith. You'd often see a linebacker on the inside or a safety over top with the cornerback in order to limit the balls thrown his way. Since the emergence of Hakeem Nicks, the opposing DC cannot figure out who to limit. So, every passing play the Giants have, there is going to be some one or some area on the field that we can exploit for gain. If our offensive line continues to play like they have, the Giants are a better team than the team that won the Super Bowl a couple years ago.
There is no team that has the trio of playmakers the Giants have at WR. The Colts were close until they lost Austin Collie indefinitely and Dallas Clark for the year. The Jets MIGHT be close with Edwards, Cotchery, and Holmes; until Mark Sanchez can show more accuracy and poise, however, we won't see that. The Broncos WR corps don't have the natural playmakers, outside of Brandon Lloyd's emergence, to match the Giants WR corps. No other team could be on that map.
