What makes you think that I didn't read the article, I hope you are not reading the same article because the article I read is clearly a critique of IPL. because that link is clearly an anti-IPL article. Here is why :-
In addition to the IPL myths section the author goes at length to make following comments :-
"Domestic coaches say bowlers increasingly go AWOL during the first-class season, and turn up fit for the IPL."
".. the biggest trick the IPL has played is that every year an Indian side wins the most-watched, richest tournament in cricket."
"India's last year in Test cricket - their worst away streak since the '60s - was merely a continuation (you can only hope it was also the culmination) of their scant regard for international cricket since the advent of IPL"
"...the board and the players - chose to not give their best to Test cricket. The choice was simple for Virender Sehwag and Sachin Tendulkar: play IPL or the Tests in the West Indies. "
"...in 2010, India landed in the West Indies without any warm-up games, without any time to come together as a team. Later that year they rested almost the whole side for a triangular series in Zimbabwe, and finished third. Nobody chose to not play in the IPL, though."
".. Indian cricketers practically use first-class cricket to fine-tune their IPL skills. "
"Australia and South Africa are playing two-Test series. South Africa have followed New Zealand in giving up the Boxing Day Test. West Indies, partly because of the IPL, and New Zealand entirely because of the clash with it, are not fielding their best teams in Test cricket. India are not interested in giving their best in Tests."
If that is not a criticism of IPL then what is ? Ofcourse any critic of IPL is a criticism of T20 because IPL is played in T20 format.
