Just a thought... but an interesting one.
While I have never particularly been fond of sports (always being the skinny, poorly coordinated kid in school) I found this interesting perspective described regarding sports in arenas:
The venerated 11th century Torah commentator Rabbi Shlomo Yitzchaki – better known as Rashi – warned Jews away from sports arenas almost 1,000 years ago. According to the rabbi considered to be the father of all Torah commentators, the Torah admonition against "perform[ing] the practice of the land of Egypt in which you dwelled" (Leviticus 18:3) includes attendance at sports stadiums.
Other opponents refer to the construction of the world's most famous sports arena – the Colosseum in Rome – as the impetus behind their rejection of professional sports.
In 2001, Cinzia Conti, the Director of Surface Restoration at the Colosseum in Rome confirmed that inscriptions deciphered at the site say the Colosseum was built using the spoils of war. The war was with the Hebrews, and the plunder used to pay for the building was taken from the Holy Temple, which was sacked 2 years prior to the beginning of work on the Roman arena.
