Houston Oilers General Manager Ladd Herzeg is complaining that the Astrodome’s operators are doing little to convince him the National Football League team should not move to Jacksonville, Fla.

“We’ve exchanged five proposals with them in the last five days,� he said. “They made four proposals. And we gave them one proposal. Now we need to see some movement from them.�

Herzeg and the Houston Sports Assn., which operates the Astrodome and owns baseball’s Astros, are trying to get together on a new stadium lease to replace the agreement that expires at the end of the year.

The Oilers are being wooed by Jacksonville officials, who are promising numerous incentives, including a $115-million ticket-sale guarantee over 10 years.

President Bob Harter of the Houston Sports Assn. would say only that Herzeg had asked for a clarification of the latest lease proposal and that his organization complied.

The Harris County Commissioners Court has approved $50 million in improvements to the Astrodome, which is owned by the county. The improvements, however, are contingent on the Oilers remaining in the city.
