Controversy around the NFL:
* After months of sympathetic treatment, the Chargers, Coach Don Coryell and Jack Pardee, the assistant head coach, are being criticized strongly by San Diego fans and media.
Pardee was hired last winter to shore up the team's inconsistent defense, but the Chargers are next to last in defense in the American Football Conference after being embarrassed on Monday night television by Seattle.
But Pardee can't take all the blame. San Diego traded Fred Dean, the defense's best player, rather than renegotiate his contract. That severely weakened the Charger pass rush and exposed their secondary, which also is ranked 13th.
During the week before the Seattle game, the team was bothered by a statement from ex-Charger John Jefferson, who said at least eight players want to leave because of contract problems.
* Houston fans were stunned when the Oilers cut quarterback John Reaves the day after he started his second game for the team. The fans overwhelmed the Oiler office with phone calls and mail, but Coach Ed Biles stuck by his decision.
Biles explained that he had long planned to release Reaves when backup quarterback Gifford Nielsen came off the injured reserve list.
Quarterback Ken Stabler, hardly the people's choice, said there is no quarterback controversy.
"I've always maintained that I'll be the starting quarterback come hell or high water," he said.
* Even Buffalo Coach Chuck Knox couldn't tolerate guard Conrad Dobler's dreadful performance against Dallas on national television two weeks ago. The two got into a shouting match on the sidelines when Knox removed Dobler near the game's end, and the veteran guard was benched for last Sunday's game against St. Louis.
Going into training camp, Dobler figured to have a difficult time holding his starting job. He survived because his main challengers were injured. Now, he may have played his last game for the Bills.
