Rookie's submission
Model: points ? minutes · data range 28–36 min

Prediction for 48 minutes:
ŷ = 61 points
"Play the star all 48 minutes for 61 points!"
1 · What's the problem?
A line only describes the range it was fit on. Past the data the relationship can bend or break — fatigue alone would sink a 48-minute projection.
2 · So what should the rookie do?
Predictions are reliable inside the data range (interpolation). Outside it, flag clearly as extrapolation or collect more data.

Graded — stay inside the data.
A great fit on 28–36 minutes says nothing about 48. Interpolate freely; extrapolate only with a warning.
