As hard as coaches work to beat teams by 10 I think they can become more creative when it comes to preserving the feelings of the players of teams who can be beaten by 100. It's not enough to pull off your press after the half. If everything you put up goes in then stop shooting. One may reply: "Asking my players to stop shooting, or make 10 passes, or stop dribbling, or go to a sagging 2-3 zone is unfair to my players and not real basketball." If winning is the primary motivation of your programme then I agree.
On the other hand, if the primary motivation is to develop caring, thoughtful, respectful young men (this goal is not limited to Catholic education of course) then I fail to see what can be gained by beating the likes of Parkdale by 90? (I felt bad for the Parkdale team...a small 500+ inner city 60% ESL school against a 1000+ perennial powerhouse from the Burbs.) While this may not fit someone's definition of no mercy it's certainly not mercy enough.
I was far from the only coach/parent/spectator there dismayed by these lob-sided results.
I can tell you from the experience of losing to Vaughn 111-47 in the finals of their tournament in their gym that my players were not unaffected by such a defeat. I was puzzled by the host coach's decision to continue to pour it on while my bench was in for most of the second half. Perhaps he was caught up in the exciting (hostile) atmosphere of the home crowd hopping with excitement at a 100+ score? Or maybe I am to believe they stood to improve by using my bench as a dummy defense practice squad...who knows. (I must say that the players never taunted, show-boated or otherwise rubbed it in which was nice to see.)
Of course there are those who will continue to hammer weaker teams because "they have work to do" or "this is the real world of basketball" and if you can't stand the heat get out of the kitchen, but I would like to think that the majority of coaches and players are more interested in the integrity of the game and the developing psyches of the young men we are responsible for.
