They need to make rule changes to 3vs3 to keep it interesting, for example attacking zone time or time how long you can have the puck.Yeah, I agree. The end result of this will be teams playing less aggressively, not more. No matter how you structure it, the imperative in 3v3 hockey will always be possession at all costs. Tweaking around the edges won't change the fundamental nature of what 3v3 means.
