I couldn't really say that I will bet because I have knowledge and ideas of all the team's performance. I don't experience the life of a journalist, but for sure, these people are much busier than others, so free time is quite limited. If ever they have some break, that is for family bonding, not for gambling.
Gambling could make someone's mood go out of control. They'd better not get attached to it if they want to have better results from their job. If they think betting is just for fun, I think watching the game every day is a fun thing already.
