Eli Manning still has strong supporters on the Giants -- with rookie running back Wayne Gallman telling TMZ Sports he's "ride or die" with #10 ... despite having the #2 pick in the draft.
Gallman was one of the bright spots for the G-Men this season in their 3-13 season -- with the 4th round pick out of Clemson flashing some real promise toward the end of the season.
Now, with the team at a crossroad -- stick with Eli or draft a QB -- Gallman is ready to pick a side ... and he's rockin' with the guy who has 2 Super Bowl rings.
He's also got a message for teams sleeping on the Giants next year ... get ready for a comeback.
