I think the standard of pitches have played a huge part in the evolution of the game. Even in the early days of the PL, pitches were boggy marshes throughout winter. A neat, tidy passing game would be nigh on impossible to play because of all the bobbles and inconsistencies in the pitch. A ball hoofed from defence up to attack takes those variables out of the equation.
Now pitches are smooth all year round, there’s less need to go route one because that sorter passing game is easier to play and isn’t going to be interrupted by divots & puddles and the like. This is also probably a reason why Spain became the birthplace of Tiki-Taka, because it’s got an ideal climate where it rains just enough for pitches not to dry out, but not too much that they become sodden.
I’ll always remember something my manager insisted on when I was playing youth football, maybe 30 years ago, that I disagreed with then and has aged even worse.
Never play a throw in backwards.
The game back then was very much modelled around gaining territory. Working the space, playing the ball back to find new paths and switching the play we’re not really in the agenda, it was all about keeping the ball up the other end.
Admittedly I played for the worst team in the league and it was on recreational pitches, both of which undoubtedly contributed to that approach, but it was something you’d see from professional teams too.
