“Stick to what you do best”, ma use to say.

Kevin Costner’s old lady seemingly gave him the same advice.

The actor’s doing yet another sports-themed movie – he’s currently filming the football flick “Draft Day” – this one about a high-school track team, according to Variety.

Costner’s “McFarland” will see the “Field of Dreams” star play the coach of a high school track team, working in a mostly Hispanic high school, whose team must beat the odds to become winners. You know the drill.

“North Country” helmer Niki Caro is directing.
