According to the text,

Sports addictions are real and do conflict with relationships. As with anything that can be addictive there is a threshold where something healthy becomes unhealthy. Addiction is defined as "the state of being enslaved to a habit or practice or to something that is psychologically or physically habit-forming". An addiction to sports is not always a bad thing, but can be. Often this addiction comes along with another addiction whether it be cigarettes, alcohol, or gambling.

If you or someone you love is addicted to sports make sure you approach it in a proper manner. If this is your spouse and it is coming between you and him/her then you may want to seek counseling. If you personally are addicted to sports then try picking up another hobby because you may just have too much free time. Get out of the house once in a while and enjoy life. Don't let the athletic ability of others control your life.
Signs of sports addiction: mood swings during events; outcome ruins your day or even week; sports gambling; fantasy sports; attending an excess number of events; excessive merchandise; arguments and fights.
