Most of us have played on some sporting team at one point or another. And we know the cliches about teamwork and the chain only being as strong as its weakest link, etc.
But the rule that most of us tried to abide by and most pros obviously try to as well is a simple one: don't be a bad teammate.
Using common sense with this rule would include:
1) Not throwing teammates under the bus to the media and/or the cops.
2) Not spreading rumors about teammates.
3) Not beating them up.
4) Not dogging it on the field and leaving the team vulnerable.
5) Stay away from teammates' wives, sisters (unless given permission) and other close relatives.
That pretty much covers the rules of being a good teammate.
This list might be controversial but I will use facts (or strong rumors) as my defense.
