Football is not a very popular sport in the U.S. To make more people

Football is not a very popular sport in the U.S. To make more people like the game and watch it on TV (and therefore bringing in more money from commercial ads), the football association proposed several changes to make the game more active and attractive. One of the suggestions is to grow grass on the football fields that would be water resistant on the surface. This will make the game run smoother, as often times football players slide on wet grass and therefore lose the ball.

Which of the following is a better suggestion, the one that will make the game more financially attractive to football clubs and investors in the U.S. and other parts of the world?

a. Building stadiums with roofs that cover 100% of the stadium is considerably cheaper than using water resistant grass in U.S.

b. Football games should be advertised more on TV in order to attract such audiences that never watched football before. This is an unsure solution, as the ROI in this case is doubtful.

c. U.S. needs to attract more foreign players to make the games more attractive by offering them such benefits that they cannot refuse.

d. Research shows that planting water resistant grass is very ineffective as it increases the costs of running a stadium and would not enable football stadium owners make much profit off the sales of the tickets. Therefore, investors should invest more in the football players' shoes to make them run smooth on wet surfaces.

e. Football should cease to exist and more money needs to be channelled in other sports, like baseball and american football. More investments into popular sports will bring in more profit off the sports.
