27 teams have gone into admin since Leicester pulled their fast one in 2002, one has just been promoted to the Prem, six play in the Championship with us, twelve are in leagues one and two but an alarming eight have dropped out of the league all together!!!
According to
this page on wikipedia there are 19 clubs who've had deductions after entering administration (in one instance — Rotherham Utd — twice), and another 8 who entered admin
after Leicester City but who weren't given a points deduction. Their fates since then are as such:
Wrexham (2004, -10 pts) League One -> Conference
Cambridge Utd (2005, -10 pts) League Two -> Conference
Rotherham Utd (2006, -10 pts) league One -> League Two
Crawley Town (2006, -6 pts) Conference -> League Two
Boston United (2006, -10 pts) League Two -> Conference North
Leeds Utd (2007, -25 pts) Championship -> Championship
Luton Town (2007, -30 pts) League One -> Conference
Bournemouth (2008, -27 pts) League One -> League One
Rotherham United (2008, -27 pts) League Two -> League Two
Halifax Town (2008, -10 pts) Conference -> Conference North
Darlington (2009, -10 pts) League Two -> Conference
Southampton (2009, -10 pts) Championship -> Championship
Stockport County (2009, -10 pts) League One -> Conference
Chester City (2009, -25 pts) Conference -> Dissolved (2010)
Northwich Victoria (2009, -10 pts) Conference -> Northern Premier
Farsley Celtic (2009, -10 pts) Conference North -> Dissolved (2010)
Salisbury City (2009, -10 pts) Conference -> Conference South
Crystal Palace (2010, -10 pts) Championship -> Championship
Portsmouth (2010, -9 pts) Premier League -> Championship
Plymouth Argyle (2011, -10 pts) League One -> League Two
As you can see, every Championship side to enter administration and be deducted points has eventually returned to this level. The worst two examples would be Farsley Celtic and Chester City, both of whom were eventually dissolved. Then you have Luton Town, Boston United and Wrexham who have dropped two divisions. Everyone else is no worse than a single division lower, and in the case of Crawley Town, they've actually achieved promotion to above their original stature!
My point here is that the statistics you presented initially painted a somewhat bleak picture for administration which I don't think is realistic. Yes, we will
probably be relegated to League One. We may well find we're stuck there for a while, but it's certainly plausible we can achieve promotion back to this division, and we shouldn't be overly concerned with the likelihood of plummeting down the leagues.
