There is kid whose family I know who plays for a crosstown High School. Kid started at Shortstop on Varsity in the beginning of the 2016 season but got moved to RF midway through the season due to too many errors. I asked the kid how many grounders he got at team practices, he said "none, ever."
OK. I later asked the Dad how many grounders a day the kid got outside of team practice? He said "zero". I'm thinking, yeah that doesn't sound like a Varsity Shortstop.
