As my son was 18 this year (and has been a regular at the CG for a lot of that time), I got to thinking just what I had got him into so checked back to see the high & low lights of that time.
In the seasons since he was born we have
3 x Relegations (1999-2000, 2005-06 & 2010-11)
2 x Promotions (2006-07 & 2011-12)
3 x Play-Offs (2003-04, 2009-10 & 2012-13)
1 x Play-Off Final (2009-10)
Average League Position: 10th in League 1 (which is probably the same over most of our lifetimes too)
Best FA Cup: 4th Round (Leicester away 2010-11)
Best League Cup: 4th Round (Aston Villa Home 2012-13)
Best JPT: Final (Chesterfield 2011-12)
So whilst the first few years (where we didn't go that much) were fairly quiet, the last 10 years has seen us promoted, relegated or in the play-offs in most years (7 of 10).
You didn't count the two promotions and one relegation in the one year !
Promoted to Prem, relegated to Div 2 (then 3rd level), then promoted to Div 1 on appeal.
Or was that just before his time ?
