Roger Montgomery (and his Montgomery Sports Group) is the agent that signed JLin out of college. Montgomery Sports Group is a one-man shop. His one-man company is so small and of such limited resources that he regularly outsourced much of his needs like accounting and legal or whatever, I think, like having an outside lawyer double check the legalese of contracts instead of having in-house staff that could do it.
When Linsanity hit, the massively multiplied needs (companies offering endorsement deals, media outlets seeking interviews, etc.) outstripped the resources of a single one-man shop. But Jeremy is loyal to a fault. So instead of moving to a larger agency with more resources, he decided to stick with Montgomery but hire more agents.
There are two types of agents in the NBA. One type is the traditional agent that takes a percentage of the money a player earns. Then you have the second type of agent who does not take a percentage, but instead provides services on an a la carte basis, either charging by the hour or per service, such as negotiating a contract with a team or an endorsement deal or whatever.
Some (Melo, Wade, Bosh, etc.) choose the first type and pay a percentage. Some (Tim Duncan, Grant Hill, Ray Allen, Marvin Williams, Thaddeus Young, etc.) choose the second type which tends to be cheaper since you only pay by the hour instead of forking over a percentage.
Jeremy pays for BOTH types. He's loyal to a fault and unwilling to ditch his original agent. So he's paying a percentage to Roger Montgomery. In addition, since Montgomery's one-man shop doesn't have sufficient resources, he's also paying another agent Jim Tanner (Tandem Sports & Entertainment) by the hour.
At the time that JLin hired Jim Tanner after Linsanity's debut required greater resources, Tanner was working as part of the sports department of the prestigious D.C. powerhouse law firm Williams & Connelly (represented Bill Clinton during impeachment, Oliver North during Iran Contra, Regan would-be-assassin John Hinckley, etc.). Other clients were Shane Battier, Tim Duncan, etc.
Tanner subsequently decided to strike out on his own and form Tandem Sports & Entertainment with a fellow lawyer from the sports department of Williams & Connelly. Jeremy followed his agent Tanner to the new firm.
So Jeremy currently has multiple agents from different agencies simultaneously representing him. Roger Montgomery, his original agent that he's kept, paid by percentage. And Jim Tanner, who charged by the hour at Williams & Connelly, and I assume does so at Tandem Sports & Entertainment as well.
I don't think any other NBA player does this. No other player I know of is simultaneously represented by two separate agencies. They either go with a traditional agent and pay a percentage, or go with someone who charges by the hour. Jeremy is paying via both methods to two separate agencies and sets of agents, or possibly more since I think he may also have a third agent handling Asia stuff. All because he's loyal to a fault and unwilling to ditch his original agent even after his needs outgrew the resources of a small one-man shop after Linsanity.
During his Taiwan testimonial, he mentioned how Montgomery gives him advice and helped him with perspective.
I guess Roger Montgomery has finally decided to merge his one-man shop (Montgomery Sports Group) into a bigger organization. The tweet says Montgomery is joining Roc Nation Sports.
Roc Nation Sports was the agency founded by Jay-Z, who was a minority Nets owner at one point. The chairman of Roc Nation Sports is Michael Yormark, brother to Nets CEO Brett Yormark.
I guess this ties Lin tighter to the Nets and allows for better global marketing synergy and coordination possibly, as the Nets try to expand their fanbase. He really is investing all the way into this Nets "startup." Not only will JLin be working under a Yormark, but one of JLin's two agents will also be working under a Yormark
