I think my point is being slightly missed.
I want kids to play AS MANY sports as possible.
A great book called "Range" by David Epstein should be read by all sportspeople, not just coaches. It highlights that, not even in sports, but in general life, you shouldn't become a specialist until it's required.
To bring this back to sport, though, when basketball was smaller and less popular than football, the consensus was "we have to sacrifice because otherwise our sport will cease to exist"
But now basketball is bigger, and the mindset from football clubs/people is the same as before.
But as a coach I deal with many multisport athletes and:
Soccer/Basketball athletes - 0 issues
Tennis/Basketball athletes - 0 issues
Cricket/Basketball athletes - 0 issues
Athletics/Basketball - 0 issues
Swimming/Basketball - 0 issues
Hockey/Basketball - 0 issues
Football/Basketball - Have had football coaches call me to not play a player as much, ask if the kids can miss multiple trainings, pressure kids to not play basketball as "risk" of injury, coaches have put pressure on players at U16 level saying they need to pick a sport now or they wont play to A grade side.
As a coach, I have never put pressure on a player to stop playing another sport, or to miss other sports events, or inferred that another sport is bad for them.
My point is steadfast as other sports and basketball seem to work well together.
Basketball cannot be expected to accommodate every sporting code, and mathematically, football is the least played sport by junior athletes; therefore, working with/around football would be the least efficient option and the least effective at capturing a market. Football should be trying to work with basketball, as basketball holds some of the most junior athletes.
I agree basketball is missing the "club culture" element, and it's up to the clubs to find a solution to that. A mindset shift is due from the football side, in my opinion, as now the little sport is the biggest, and it's time that the other codes show the relevant respect.
