Manziel also said Erik Burkhardt will be his agent and Bradley Beckworth and Jeffrey Angelovich are overseeing his business-related matters.
The relationship with LRMR and Carter has been developing for some time. James said last week that he texted Manziel regularly throughout the quarterback's final season at Texas A&M. And when Manziel was deciding who to align with, Beckworth said the model that James followed was one that was most appealing.
Beckworth said after reviewing management models, the Manziel team was "most impressed by one uniquely established for the NBA's LeBron James."
