Amani Toomer says losing Mario Manningham is going to have an impact on the Giants offense.

Manningham signed with the Niners last month in free agency because the Giants weren't going to pay their third wide receiver knowing that eventually they will have to take care of Hakeem Nicks and Victor Cruz.

Toomer, though, wonders what the Giants will do without Mario.

"Losing Manningham, that third playmaker," Toomer said while making an appearance at the opening of the NFL pop-up store in Manhattan. "It’s easy to take two receivers out of the game –- easier –- especially when your running game isn’t going as well as it had been in the past. And the tight end position really isn’t a threat. Now you have to look for someone else to make the plays or get their running game going because there’s going to be a big vacuum there without him."

Toomer also was asked about his Twitter back-and-forth with Jeremy Shockey a few weeks ago that caught the attention of a lot of people.

"Whatever happened was regretful," Toomer said. "Live and learn, right? I tweet a lot like that. Didn’t know that it would catch on. It’s not out of the ordinary for my tweets. Now that I’m not a player anymore I can give more of my opinions."

"I felt there would be a groundswell of people wanting the return," he added of a report that said Shockey was interested in returning to the Giants, which sparked the Twitter beef. "And I felt like it was… well, you know what I wrote."
