The Dallas Texans were back home Monday with their third victory in four American Football League starts -- a 19 -- 12 triumph over the Denver Broncos -- but their visit will be a short one.

The Texans have two more road games -- at Buffalo and Houston -- before they play for the home folks again, and it looks as if coach Hank Stram's men will meet the Bills just as they are developing into the kind of team they were expected to be in pre-season reckonings.

Buffalo coach Buster Ramsey, who has become one of the game's greatest collectors of quarterbacks, apparently now has found a productive pair in two ex National Football Leaguers, M. C. Reynolds and Warren Rabb.

Rabb, the former Louisiana State field general, came off the bench for his debut with the Bills Sunday and directed his new team to a 22 -- 12 upset victory over the Houston Oilers, defending league champions.

``Just our luck!'' exclaimed Stram. ``Buster would solve that quarterback problem just as we head that way.''

Ramsey has a thing or two to mutter about himself, for the Dallas defensive unit turned in another splendid effort against Denver, and the Texans were able to whip the dangerous Broncs without the fullbacking of a top star, Jack Spikes, though he did the team's place-kicking while nursing a knee injury.

``Our interior line and our linebackers played exceptionally well,'' said Stram Monday after he and his staff reviewed movies of the game. ``In fact our whole defensive unit did a good job.''
