I agree with you on those points. They still had something to play for though for most of the season for nearly every team across the 92 teams, other than the bottom few in the old fourth division. There will always be dead rubbers, but far many more when you take away the threat of relegation on the field of play. There will also always be a decrease in motivation (eg why would London bother spending money to compete), interest (why should I go to watch my team try and win the league when even if we win it I already know we will just be stuck there next season) which in my opinion eats down at a sport from the top, isolating fans
