You say there's no benefit with BOL and that kickball is even worse...yet offer up no alternative solutions. Forcing youngers to play out of the back is a great way to get away from horrible kickball games that we know the youngers can devolve into quickly if the BOL rule did not exist. Most U-10 teams (and younger) do not know how to play out of the back effectively...and that's OK. It's a learning process that takes years to develop and the BOL is helping them to think of basic passing/spacing concepts at an earlier age.
If we want to improve as a soccer nation then we have to get away from the immediate gratification impulse and understand that it takes time for soccer players to develop. Enjoy those moments when your team is stringing together 2, 3 or 4 passes together. I would rather see our team making an effort to pass and lose than playing kick ball/high pressure and getting a win.
As I stated before, a better solution is to educate coaches on building out the back (specifically make coach training more readily accessible and cost friendly) instead of legislating changes to how the game is played. I'm not inherently opposed to the BOL; however, its "cost" of changing and slowing down the game is not worth the limited "benefit" it provides which for the most part is only temporary. BOTB requires players to be able to make quick decisions while under pressure, as opposed to stopping the game and moving everyone up field so little Johnny can get an uncontested pass. I get it, teaching BOTB is a disaster when youngers are first learning and drives uneducated parents crazy when their kids give up 5 goals trying to pass out the back. However, what's the point of delaying the inevitable for a few years? To me the BOL is just a crutch and are like training wheels on a bike, it gives people comfort but actually delays the learning of the skill. My other recommendation is futsal, while not apples to oranges, it does provide a good foundation for playing out the back.
