There are like 6 posts defending a video that would get most high school coaches fired if they said the same thing.
It is also not true. Youth and high school basketball has changed a lot in the last 10-15 years. Generally it is catholic vs catholic in the D1 state tournament after the second round on the boys at least, but the #1 team in Division 1 right now is Staples. Not exactly a city team. Ridgefield and Southington are also in Top 10 of D1. New Britain is #2 and Danbury #8 in Girls D1, but Greenwich and Southington are also in the Top 10 on the girls side. The Top 3 D2 girls teams are Rocky Hill, Trumbull and Staples.
Last year's boys D1 playoffs was dominated by Catholic Schools, but only two city teams, Hillhouse and Crosby, even made the second round of the D2 bracket. If you want to make Manchester a city team for this argument, then you have last year's D2 champion, but making that case is playing to the stereotype that I was talking about.
The kids work hard to get to a high level, they aren't just born that way as Titus' stereotypes imply, and AAU tournaments are by talent level, not city vs. suburb.
