First its it worthy 36$? no sarcastic ! Well after a quick read of Puck's link, I do agree that football was becoming much faster (from passing speed to team rythm in movement) - so it's true - one can not measure (like if they did?) but one can tell the difference from even WC90's to lately 2010-14. However if one say that speeding game is part of the "evolution" of football? it's a good question *or dilemma, that Football is "supposed" playing so fast! My two cents: 1- Pros: it's good for entertainment value, as most people seem having no time now aday then back then - so speeding teh game is likely to keep people hope alive for a gaol happening at any time .. "SOON" - hence more tickets selling more shirts selling ! 2- Cons: if one play football, he should notice that speed would kill the precision and agility of a player - more like chancing in a "premade system" - Example of Tikitaka, Xavi has notime to think but (reflex) pass square to the left where he knows (pre-made) Iniesta should be there or he coule make a quick thruball where Messi would be available. So once the system works, it's great fluidity and fans are amazed. A dilemma is that thsoe passes were more like a relex (at high tempo) , rather than "calculated" a la Pele of 70 or Zico/Socrates of Brazil 82 .... (in a slower speed) So your choice! If prefer basketball kinda football then this is a great time. (or evolution) But for me , it's just killing off the "human" factor in such a game = BIG DILEMMA (of a so called "evolution") and yet "evolution" often means better?!
