Answer:
False
Step-by-step explanation:
Not only coaches, but all of us are affected by our own prejudices. For example, I think that most Chinese, Japanese and Koreans know martial arts because they teach martial arts at schools in China, Japan and Korea, but they are extremely bad at any other type of sport. I've never heard of a Korean, Japanese or Chinese national team winning at any professional sport, so I personally have the prejudice of believing that they are really bad at sports. On the other hand, I like to play football and I know that large guys are god for my team, so if I had to choose, I would hand pick the largest players.
Sometimes prejudices are not necessarily bad, and coaches that have several years of experience may seem to be unfair, but unless proven wrong, their prejudices are not based on crazy ideas. I'm 6' 3'' and weigh 220 pounds, and I play football and basketball. I would never choose a guy that's only 5 ft tall to play on my team. Maybe I'm wrong, but until proven wrong, I will follow my own experience and prejudice. And a coach has seen much more athletes or would be athletes, and probably knows better than me.
