Don't remember much of anything about Grant, but as a Knicks fan in the 70s remember their uncle Glen ("Gondo") Gondrezick well. He spent six years in the NBA.
In case you didn't know, Glen died in 2009 from complications of a heart transplant. See
this obit.
The sisters and their family have all kinds of stories to tell, some of which are mentioned in
this MaxPreps article, including the head-on crash that their mother and the sisters survived. Their mother coaches their high school team in Benton Harbor. She took over from her father, Lou Harvey, who became a Michigan legend during his more than two decades coaching the Benton Harbor girls basketball team.
Benton Harbor, by the way, is on Lake Michigan in the southwestern part of the state, and it's less than an hour from there to South Bend, so the family lives closer to the Notre Dame campus than Michigan's.
One last bit of trivia: at one point, ASGR had the two sisters ranked #1 in the nation in their respective classes. ASGR has since moved them down, but they're both still highly rated. Blue Star has Kalabrya #7 in 2015 and Kysre #8 in 2016.
