I see nothing wrong with them...if someone has the speed and bike control to literally remove you from play without broadsiding or ramming you or playing dirty in any way then I think that's just part of the game. if you don't want to get screened figure out how to avoid it...ride faster or smarter or in other words outrun or outthink. it's not like screens are a make or break tactic in this game...because it's 3v3.
even if you play 3 forward (no goalie) against 2 forward (permagoalie) and both offensive players screen both defensive players for the forward with the ball that still leaves 1v1...forward vs goalie. if that is an automatic goal then play without a goalie. but if the goalie wins the ball on a block, deflection or charge it's a breakaway against an undefended goal...no goalie and the defense is too out of position on screens to stop the breakaway.
if you both play 3 forward or 2 forward then it's still just 1v1 after an effective screen...either 1 forward vs 1 defender or 1 forward vs goalie. 1v1 is going to happen in this game..and should.
screens on offense stop teams from stacking defensive players in front of the goal and the offense can screen the stronger defensive player and get a better matchup 1v1 for their forward with the ball.
screens on defense are technically just one on one coverage...shutting down passing lanes in order to make the forward make a bad pass or have to beat the last defender(s)/goalie alone...which shuts down the option of last second 2v1 near the goal.
someone tell me the complaints about screening...that it's too hard to play 1v1 offense/defense or that it's unfair when someone is more maneuvarable/faster/beter on their bike and keeps you from getting the ball. feel free to cite other sports...
People complain about screens/picks? As long as you aren't cutting people off so that they crash into you, screens are a great and skillfull tactic.
