All teams will suffer a tough loss sometime during their season. A string of losses becomes known as a losing streak. The question becomes how do you stop the losing, or overcome that tough loss?
Have a short term memory (both in winning and losing), work harder in practice, listen to your coach, and don't point fingers at the others on your team.
Sometimes you just might be the inferior team. Don't think about the end result. Instead, focus on the things that you can do to make your team better.
