Forfeiting a given match is all about strategy and it it no one's business but the coach's as to why he chooses to. I know that you have to take into account that when you have a young team of inexperienced wrestlers, sometimes you sit a kid because of injury, and sometimes you sit the kid who you know won't last 30 seconds, and may very well get injured in the process. You also need to be careful not to set new kids up for failure before they develop a love of the sport, because they will often end up hating it and quit if you throw them to the wolves. That being said, different kids will handle things differently, and as a coach, it is your job to figure out who will and who won't be able to handle given situations.
