The NY Giants need franchise QB Jaxson Dart on the football field ... and that's why former star running back Brandon Jacobs is imploring the young player to SLIDE!!!
TMZ Sports spoke with the two-time Super Bowl winner earlier this week after Dart took another hard hit during Big Blue's November 9th game against the Chicago Bears, forcing him out of the game with a concussion.
It was the fourth time Dart was forced into the infamous blue medical tent ... and while Jacobs loves JD's mobility and playmaking ability, he's pleading with the rookie to learn how to avoid big hits.
