I have no issue having two whistles in the dasherboard indoor or Futsal. This is generally no issue. But... the playing field is significantly smaller and there are fewer players so proximity is generally less difficult to contend with and we're usually in decent enough location to have reasonable angles built in for most challenges... In the bigger field there is a really important thing with occupying space in the middle of the field which seems to get lost when you bring in another whistle. If you're going to go there, might as well do what West PA does and use 3 whistles like their HS system... Don't lose the middle third. ..... If you want to increase scoring in soccer... you know what you do? Make the field smaller and reduce the number of players to 5 each. I mean then you can have line changes and... oh you've just invented futsal... which has an average of 5.96 goals per 40 min game which gets you to 13.41 extrapolated a 90 min match... how much attacking are you looking for and why because at some point it becomes a different game.
