I'd rather win games than lose games, to weaker opposition.
This isn't aimed at anyone but some complain we don't or can't play with big game mentality, so using these games for team building or enhancing our team cohesion adds to this. It shows we're not playing down to the opposition and more importantly learning how to work together as a team, in order to win.
Regardless of who our opponents are and their quality/strength, it reveals a lot about the team's progression. It tells us what the team's attitude is and what their motivational levels are. Even whether everyone is pulling their own weight or not. It also shows if we've improved in any areas that have been challenging for us.
It's not only a reference point to determine growth but another opportunity to teach them how to win at all costs.
A frequent complaint I've often heard is our poor decision making and inability to take calculated risks that benefit the team. These are the perfect games to work on this, as they'll learn which are the better/best courses of actions and only continue to build on team trust.
