Eli Manning hit the mark recently when he shot back at Amani Toomer after the former Giants receiver admitted he thought Tony Romo, and not Eli, was the best quarterback in the NFC East. “I got some text messages from some buddies about the situation, I hadn’t heard about it, kind of researched it a little bit, saw some of the comments, I kind of laughed about it a little bit,’’ Manning told The Post Monday morning in a phone conversation during a break from promoting Gatorade’s “Beat The Heat’’ program.
