You have to put the quote in context.
Ever since the IPL came into existence, the second anything goes wrong with Indian cricket, IPL is among the first things to be blamed ! Till now I was wondering why ppl have not blamed the IPL for this debacle. Thats just the way things are in Ind media. The second something goes wrong, someone will find a way to blame the IPL for it. Take the question for instance, - give up IPL to work on test cricket? IPL lasts a month and half, there is still plenty of time for players to work on test cricket.
Its become the norm, and the truth is just left field connections being drawn with the IPL and poor performances, are quite frankly the norm now and obviously irritating for Dhoni to answer everytime a tour goes wrong, so I can understand his frustration. If an Indian cricket sneezes some nut in the media will find a 'creative' way to blame the IPL for it.
I am not the biggest IPL fan there is, but I am also not a fan of scape goating and the IPL is the media's fav scapegoat for everything. If ppl believe what happened in the past three tests is because of IPL then thats nuts but like I said someone will find a way to blame the IPL. Never mind that well after IPL was formed Ind have had good results (WC, CT and Test #1 were all after IPL had been up and running), then IPL is conveniently forgotten. However the second something goes wrong, IPL is the first thing targeted. After Lord's IPL was no problem, but when things went down, IPL is the reason. IPL is just a month long league, which doesn't decide the fortunes of Ind cricket either in the good or bad. The WC was not due to IPL and this defeat was not due to IPL either.
The same question could be - Should Indian players give up on playing the somewhat meaningless, ODI and T20 matches that follow to go work on test cricket? Will that question be asked, of course not. The point is because of the high earnings from the IPL (Yuvraj earns more than Hazard for instance), for the media IPL has a target on its back and they cannot not blame the IPL for anything and everything. Ind cricket fans tend to over-react after bad results, are quite famous for it actually, so highlighting IPL and all the riches it brings is a way to feed off that angry reaction and attract readership. Players earn so much and yet this result, is bound to get readers in, so IPL bashing is an easy bait to get in new readers.
So this 'jealousy' comment is more for the Ind media than outside world. The IPL is full of outside world players from all over playing the IPL (except Eng because of competing leagues issue and Pak which is due to the aftermath of 2008 terror atts). The media does though keep looking for opportunities to jump at the IPL whenever possible, which is basically everytime Ind loses a match.
