For the most part, it has been common practice among the better agents in the NFL, and around the sporting world, to make sure that they scrub their clients’ social media pages of questionable material that they may have posted over the course of their lives leading up to the draft, in whatever respective league they may be looking to enter.
While it’s hard to imagine something so incriminating as to prevent one’s entirely being drafted to go unchecked for so long, there’s no doubt that some posts on social media can damage a player’s stock. It could speak to character issues that some teams more than others would be inclined to consider grounds for removing entirely from their draft board.
