People always make too big of a deal over players getting into it during practices or timeouts and what not. I actually love seeing this kind of behaviour from players, as long as it isn't a reoccuring thing. It shows that they are passionate and aren't happy with what is going on. In the Grizzlies case, they got off to a very slow start and with Mayo and Gay both being very competitive players, they let their competitiveness get the best of them and it caused a bit of an exchange. Highly competitive people don't deal well with losing and there is nothing wrong with that, especially in professional sports. A similar thing happened to the Toronto Maple Leafs earlier this season as they got off to a horrid start and two players got into it at a practice. Since that incident both players involved have played much better and the team has played better as well. I would much rather have a team full of players who get absolutely pissed off when they are losing, even if it means that they cross the line on occasion, than a team full of players that seem content with losing and don't get upset by it. I would absolutely love to get home from school and read about Chris Bosh and Andrea Bargnani getting into a bit of a fight/argument at practice because it shows that they are pissed off with how the season is going and, at the very least, shows that they have some pride.
