Eli Manning’s most prolific seasons came under the tutelage of quarterbacks coach Mike Sullivan. Now, after a yearlong sabbatical, Sullivan is back with the Giants and he said Manning’s arm is as strong and lively as ever.
“I don’t think his arm has ever been stronger. He has a very live arm. He looks like he has a lot of zip on the football. He’s worked hard to take care of his body, and work on the fundamentals, make sure he’s able to do all the things necessary,’’ said Sullivan, who was rehired on New Year’s Eve and still finds Manning doing all those necessary things a dozen years into his career.
