Start at your own 20 — 80 yards to the end zone. Score it.
Every down is a golf hole: you get a list from the league you picked (NFL or NBA) and a rank. Name the player at that rank. How far off your player's real rank is picks the play. The window is half the rank (at least 3, at most 15): #10 allows 5 off, #20 allows 10:
Four downs to gain 10. Touchdown = 7.
Field goal (3) once you're within 50 of the goal line: one hole, and your player just has to land within the window. 30 yards and in is a gimme (±30), under 50 is easy (±10), 50+ is medium (±5), 60+ is hard (±2).
Score and keep going: every touchdown or made field goal starts a new drive from the own 20, and your points and yards carry. A missed kick or a turnover on downs ends the run.
