If people are still talking football, it's about Washington's victory over Miami in Super Bowl XVII, not this Sunday's Pro Bowl, the low-intensity all-star contest that seldom attracts much attention. So before we all bid adieu to discussion of the National Football League and its championship game, herein some parting observations:
* Isn't it interesting that some observers have called Super Bowl XVII the NFL's most exciting roman numeral game ever? Interesting because there were more rushing plays and fewer pass completions than in any Super Bowl. Teams obviously don't have to play ''throwball'' to make things entertaining.
* Congratulatory phone calls from the President, made famous during the Nixon administration, achieved new orchestrated heights after Super Bowl XVII was over. Both coaches, Washington's Joe Gibbs and Miami's Don Shula, received calls from President Reagan in their respective locker rooms. The conversations were seen and heard by a large nationwide TV audience, hardly the most ideal way to carry on a meaningful dialogue, particularly so soon after a tremendous victory or crushing defeat. If this sort of thing becomes any more faddish, we might expect the president of the American Farm Bureau to place a call to star ''Hog'' John Riggins should the Redskins repeat as champions. Or maybe the coaches will have to start leaving messages in case they're temporarily unavailable: ''Sorry, I'm in the shower now, at the sound of the beep please give your name and. . . .''
* No sooner had the Redskins become champions than two ex-Washington players were named to the 1983 class of the Pro Football Hall of Fame. Quarterback Sonny Jurgensen and halfback Bobby Mitchell, now the team's assistant general manager, will be enshrined in Canton, Ohio, this summer. Joining them will be Kansas City linebacker Bobby Bell, Miami wide receiver Paul Warfield, and San Diego coach Sid Gillman.
* Joe Gibbs, many insiders feel, is no flash-in-the-pan as a winning coach. This has become a hot topic because of the collapse of the San Francisco 49ers under Bill Walsh this season. Walsh was hailed as a genius just a year ago.
