I don't think it's bad sportsmanship to try and win a match by scoring points by any means necessary to win. You don't revieve points in wrestling for illegal moves or unsportsmanlike conduct, and trying to tech fall a kid if they're terrible on their feet isn't bad sportsmanship, it's smart. Someone alluded to football earlier, so here's another: you're going to throw the ball to 6'5'' recievers who can run 4.4 40's when the d-backs are 5'5'' and run 5.0's.
