CITY HAS LOST JETS TO JERSEY, KOCH DECLARES
The New York Jets have rejected the city's offer for a new lease at Shea Stadium and, beginning next year, will play their home games at Giants Stadium in New Jersey, Mayor Koch announced yesterday. The Mayor made the announcement at an unusual City Hall news conference where he and other city officials made frequent derisive references to Leon Hess, the Jets' owner. They said their inability through six months of on-and-off negotiations to persuade Mr. Hess to stay in New York was not a result of financial considerations. The city, they contended, had offered enough incentives so that the team would fare no better by moving to New Jersey. The officials said they learned of Mr. Hess's decision Monday. Mr. Koch said he believed that Mr. Hess was moving because of an ''emotional matter'' between Mr. Hess and M. Donald Grant, the former chairman of the board of the Mets, the baseball team that is the primary tenant at Shea Stadium.
