Eight Oxfordshire teams are still challenging for titles or stuck in relegation trouble with just a handful of games to play.
Chinnor, Wallingford, and Bicester all look strong bets for promotion, while Chipping Norton are bidding to go up as BB&O Premier Division champions.
Things look bleak for Henley Hawks in National 2, while Henley Wanderers are battling to avoid the drop from South West 2 East.
Lower down the spectrum, Harwell are in a strong position to replace Wheatley in the BB&O Premier Division as they are the highest ranked first team in either of the feeder leagues.
Littlemore, who re-entered the league structure from the bottom this season, could well be promoted to BB&O Division 1 South.
The equation is simple for Chinnor, who are bidding to return to National 3 South at the first time of asking.
Should they win their final three matches, Chinnor will be South West 1 champions.
Wallingford lie second in Southern Counties North and are rapidly gaining on leaders Olney.
They, like Chinnor, are guaranteed a play-off spot, but will probably need to finish the season with three straight wins to ensure home advantage.
Bicester will join Chippy in Southern Counties North if they win at Abingdon on Sunday.
A win at Swindon College will effectively guarantee Chippy the title due to their massive points difference advantage.
Henley need a miracle to escape the drop from National 2 and will be relegated on Saturday if Redruth and Blaydon win.
Wanderers are in the relegation zone, but have the bottom two sides, Windsor and Tadley to play, so all hope is not lost.
