Just to throw a spanner in the works - I was a school
teacher for 10 years and coached sport up to first team levels
If you think armchair critics are bad, trying explaining to
an irate parent why their child (who is always the best of course) has been
left out of the squad and replaced by a player of colour.
Why not just encourage kids to play the sports that they like?
If they enjoy them enough they will try to be the best they can be, which might
make them the best in their position and allow them to be picked for the team
with nobody moaning either about their being a quota or the coach being blamed
for a lack of transformation.
