Team effort can take you so far and any team needs star quality and a lot of luck. Great post and happy to see you including the family in these sporting events as this is a big part of growing up and keeping the interest in sport.
Ya, I suppose it is almost always a blending of the two. You won't win anything without some team spirit and cohesion, but equally you won't win anything without some star quality and ability within the squad. The very best coaches are able to take a team with limited star quality and instill a ferocious team spirit within them, where players play beyond their usual or previous abilities - they unlock that extra potential that is within all humans and those are the kind of teams I love to watch the most and to see them achieve success is special - Leicester City in 2018 is a good recent example.
As for family and sport, yep, it is so important and is something I did with my own Dad, so I guess it was handed down and I am even more fanatical about sport than my Dad!
