So Jack Kent Cooke finally wants a new football stadium {Sports, Aug. 22}. Redskins fans shouldn't be shocked, because while RFK is a fine stadium for baseball, attendance-wise it's the Fenway Park of football. Since the Redskins are of great importance to the District, the city should do all it can to help Mr. Cooke build his dream stadium, including condemning land and possibly providing a low-interest loan. But ultimately he must foot the bill.

Some owners, such as Edward Bennett Williams, are rich enough to run a sports franchise, but would find it very difficult to pay for a new stadium with their own money. For them the state can build a stadium in exchange for a long-term, ironclad lease. For Mr. Cooke, however, a $100 million stadium is pocket change; to build him a stadium would be a waste of tax dollars. Nevertheless, the District should give Mr. Cooke plenty of help and incentives to build the sta-dium.

A new stadium would be nirvana for Redskins fans, but the last thing the Redskins, the National Football League and the fans need is a domed stadium with artificial turf. Most 'Skins followers would be satisfied with the team's going to a few Super Bowls instead of hosting one.

I hope Mr. Cooke will turn to building a replica of the Rose Bowl -- a beautiful 105,000-seat stadium with blue sky and green grass. He could name it after the man who built it -- Jack Kent Cooke. EDWARD J. CUNNINGHAM Silver Spring As much as I like RFK Stadium, I, along with the 20,000-plus persons on the season ticket waiting list, would definitely stand to benefit from a new stadium. But, please, Mr. Cooke, not a dome!

Fall in the Washington area is the most wonderful time of year -- blue skies, crisp air. Don't make us sit indoors. Being in the elements is part of watching football. Maybe it's too cold one or, at the most, two games a year, but, oh, how a Schroeder-to-Monk touchdown can warm you up on those days.

An article in Sports Aug. 17 has much wider significance. The opening of the new football stadium in Miami was hailed by Dolphin owner Joe Robbie as "a monument to a free, competitive enterprise system." Mr. Robbie has raised $100 million, and taken an appropriate risk, in building a 75,000-seat stadium named in his honor. His action became necessary, according to the story, when a referendum to increase the local sales tax to finance the stadium "was soundly defeated by voters."

That could be a prediction of things to come in Maryland. If we are allowed to proceed with the referendum to block the proposed state construction of two stadiums in downtown Baltimore City, private capital will be encouraged to do the job it's supposed to do.
