I think the only real impact will be seen in the U10-U11 range where some players are faster than the goalie’s ability to go long.
Previously, we’d seen defenders step into the box and receive a ball if they were under pressure because of a poor goal kick and the kick is retaken. Now, no safety net.
The ref said he used to see strikers with a lead step into the box as a delay tactic. It’s pitched as a way to speed up the game. Fair enough.
Personally, I’ve not seen that employed much but I guess this rule change will eradicate that as well.
I think around U12 and older, keepers (or CBs forced to take it for their keeper) should have the ability to send a goal kick to the center circle at least. That should keep the forwards honest and allow for the outlet in the back when one wants to build out.
