A federal jury on Monday ordered the NFL Players Association to pay $28.1 million to retired players after finding the union failed to properly market their images. The jury said the union owed the retirees $7.1 million in actual damages for failing to include them in lucrative marketing deals with Electronic Arts Inc., the maker of the popular “Madden NFL” video games, sporting card companies and other sponsorship agreements.

Hall of Fame cornerback Herb Adderley filed the lawsuit last year on behalf of 2,056 retired players who contend the union failed to actively pursue marketing deals on their behalf with video games, trading cards and others sports products. “I won three Super Bowls and this feels better than all of them combined,” Adderley said immediately after the verdict was announced. “I always felt I had one big play left.” Several retired players either testified during the trial or appeared in the court to lend support, including retired Green Bay Packers quarterback Bart Starr, who attended the last day of testimony on Friday.

Richard Berthelsen, the union’s acting executive director, said outside court that the NFLPA would ask the trial judge, U.S. District Court Judge William Alsup, to toss out the verdict. If that fails, it intends to appeal. “It’s an unjust verdict and we are confident it will be overturned,” union lawyer Jeffrey Kessler said. EA’s Madden game contains 143 “vintage” teams populated with no-name players that closely resemble Adderley and other retirees. Yet only active players received a cut of the EA deal, the union’s largest, which surpassed $35 million for 2008. Ronald Katz, a lawyer representing the retirees, told jurors that longtime union chief Gene Upshaw and other union leaders “betrayed the trust of their members” by neglecting the retired players, who pay $50 a year to keep their union membership.

Upshaw died of cancer in August. Kessler unsuccessfully urged the jury to award far less, arguing the union could suffer economic harm if it had to pay a large amount. “It was the only sports union that tried to do retired players’ licensing deals,” Kessler said. The union’s primary defense during trial was that EA, trading card companies such as Topps and Upper Deck and other companies paid licensing fees exclusively for active players. But the retirees represented at trial all signed “group licensing agreements” that promised the union would do its best to market their images. The jury found otherwise.
