The singles tennis team at Brookfield East High School has a real family feel. That’s because the four teammates happen to share the same parents.

Colin, Andrew, and Jonathan are triplets. Christopher is their younger brother by only 15 months.

The Knutson brothers make up the Brookfield East Singles line-up. Head coach Linda Lied says it’s easy to tell them apart on and off the court.

On CBS 58 Sunday Morning, the brothers shared what it’s like to grow up in such a competitive family.
