No it doesn´t need to.
TV money is calculated by the strength of the league / players. As player skills and player salaries are more or less directly connected (other than let´s say in the NBA, where the salary is based on plenty things but not just on ACTUAL skill), and because salaries are independet of the league level, the league strength -> TV contract -> salaries are all "in some way" connected with each other.
