We all know that Chennai Super Kings have won the Champions league T20. But an unnoticed part of it is that they've included 6 overseas players. So, is it that can an IPL team use 6 of their overseas players in a 15 man squad? When we look at past, we have had 6 teams in Champions leagues till now (2009 edition and 2010 edition). Squads of CLT20, 2009: Deccan Chargers played with 5 overseas players.(link) Royal Challengers Bangalore played with 5 overseas players.(link) Delhi Daredevils played with 4 overseas players.(link) Squads of CLT20, 2010: Chennai Super Kings played with 6 overseas players.(link) Mumbai indians played with 5 overseas players.(link) Royal Challengers Bangalore played with 5 overseas players. (link). Is it a violation of rule or its just that other teams din't have enough overseas players available? Similar example which I want to quote in this context is mid season trade during IPL III of Doug Bollinger instead of Jacob Oram, who was injured. Why din't other teams din't use this mid season trade when their players were injured? I just wanted to know more details about these two incidents, which favored towards CSK a lot. Can we say CSK have rules biased for them just because one of their owner is the then SECRETARY of BCCI? Your views on this please.
