TBH his business ventures and contract negotiations are embarrassing for anyone, much less an NFL player.
No problem with not having an agent on a rookie contract, first round picks pretty much have their deals pre arranged. But it was foolish to not hire an agent in 2020 when the Ravens approached with extension offers and he was on top of his game. Comparatively speaking, Lamar has lost a lot of dollars trying to save pennies. Also, if he performs well and can stay healthy he would be that much closer to negotiating a second extension possibly worth much more.
