Seriously, can you imagine if that rule was put in place. You'd have everyone from 6th or 7th (i.e. not in Europe) downwards to those who are just safe from relegation trying to lose on purpose to avoid a points deduction.
Also, you'd have similar situations at the top. This year for example, now Man Utd have won the title, Liverpool and Chelsea would both be pretty eagre to finish 3rd. Punishing teams for being better than other teams, is simply a rubbish idea. Sorry.
Why not switch the prize money around instead? For example the team which finishes bottom should receive the amount the champions do, and the Champions would recieve nothing. That would allow the lower teams to catch up a bit. Brilliant.
P.s. Have you heard about the rules in the SPL. They're nuts! Just look at the table. 7th has more points than 6th. Irrelevent to this thread, I know, but I thought it my duty to let you all know.
