I've got a better question:
Should Christians view or participate in sporting events at all?
It seems to me that sports are rooted and grounded in PRIDE or a desire to show one's self superior to another.
Is that what the mind of Christ is all about?
Philippians chapter 2
[3] Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves.
[4] Look not every man on his own things, but every man also on the things of others.
[5] Let this mind be in you, which was also in Christ Jesus:
[6] Who, being in the form of God, thought it not robbery to be equal with God:
[7] But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
If you ask me (or the Apostle Paul), then it seems to me that sporting events are full of strife, vainglory, and high-mindedness, and I hardly see such Christian concepts as esteeming others better than one's self being exemplified through the same.
Then, of course, there's also the ridiculous amounts of money that athletes make at the expense of those who fanatically ("fans", remember?) support them. It certainly seems like a blatant form of idolatry to me.
Not to mention all of the time that is wasted viewing or participating in such events. Time which could be much better spent serving the Lord.
