No you don't understand. The emphasis is on building a side not on metrics where you finish. In fact that particular metric is meaningless as teams can strengthen or weaken the following season.
That makes even less sense to me. So, imagine if you were a player that has the option of joining any team in the Premier League from 7th down. Are you saying you'd be just as likely to choose to join the team that finished 17th, because you think the position is meaningless, as a team that finished higher with four or even five times as many wins in the league, that scored twice as many goals, earned twice as much TV money from the league position etc etc? Because that is what you are saying. That a team that finishes 17th is potentially better than the team that finished 7th?
The idea that the next season will always be better than the one before isn't rational if you don't have a clear idea about what it is that you are building upon. You can only know what you are building upon by testing it over 38 games and by its position in the league. That's how you decide what your strengths and weaknesses are and how to best address them with the resources you have for the next season.
