Tom Brady’s deal to buy a minority share of the Raiders has "not been approved by NFL owners," and yesterday Colts owner Jim Irsay said that the league’s Finance Committee believes that Raiders owner Mark Davis is "offering Brady too steep of a discount," according to Ben Volin of the BOSTON GLOBE. Irsay, one of seven owners on the committee, "confirmed a Washington Post report" that Davis is "offering Brady 10 percent of the team," which was recently valued by Forbes at $6B. Minority shares in a team "often come at a discount since they don’t come with any voting power," but Davis’s offer "may be too generous for other NFL owners." Irsay: "The number just has to be a reasonable number for purchase price from Tom, is the only thing. If reasonable value says … that 10 percent should be $525 million, you can’t pay $175 million.” The "next opportunity" for NFL owners to approve Brady’s deal is at their winter meetings Dec. 12-13 in Irving, Texas (BOSTON GLOBE, 10/18).
