If a guy makes a commitment to a team, he should keep that commitment. If he isn't going to be fully committed, he shouldn't be on the team in the first place. Also, you just have to find a good balance. I run track in college, and we compete in the winter, but I still find time to get out on the slope. I don't get out as much if i wasn't running, but like i said there has to be a balance. If you aren't into the sport, definitely quit cause its not worth the effort.
