I used to coach ice hockey and I was fairly good at it. My teams would consistently beat teams that were significantly older and more experienced than us.
I once took over my son’s baseball team mid-season after the coach fell ill. Up to that point, the team was at best a .500 ball club. After I took over, the team began to win nearly every game and we eventually made it to the league championship game only to lose by a run or two. We did this despite my knowing absolutely nothing about baseball.
