Licorice,
I don't care how many times you ask the same question or how many people ask the same question
like any sport I can think of, any goal that is in is good...there is as much responsibility to the defender as the offensive player...shouldn't good defense stop slop?
also, it goes both ways so it all evens out in the end...not every game of course but in the big picture
the slower more controlled game is an American invention in tournament play...it was started to reduce risk and control tempo...that is where the same shot and pass series came from
but foosball is still young as a sport and like American football, over a long enough period of time you see evolution in approaches both defense and offense...used to be in College as an example it was Quarterback option run, run, run now it is a very complex "Spread" offense which is 60% plus passing (some more or less about near this)
defenses are behind on the Spread but they will catch up and eventually there will be another change...if defenses shut things down, it pushes offenses to evolve...so far, the mainly controlled game in foosball has evolved a little with the variety and pace of the game, especially in singles
but if you aren't used to tournament play and you are used to run and gun slop don't count (a very common bar rule) then tournament play might at first seem a little slow
either way, its all good...tournament rules slop counts the tempo is more control and the vast majority of shots are the same set shot series from each player but this is not a rule it is a function of strategy
