I was sitting on the john, and this topic came to mind. If you were born in a sport's offseason, go with the next season. Here's my list:
Born October 16 1981
San Francisco 49ers 81-82 Season: 13-3, wins Super Bowl
Phoenix Suns 81-82 Season: 46-36, won 1st Round vs Nuggets, Lost 2nd Round vs Lakers
San Francisco Giants 1981 Season: First half 27-32. Second half 29-23. Overall 56-55. Missed playoffs. Strike split and shortened season into 2 halfs.
