I would say so. Definate drop I think in the 'hunger' level - people not applying themselves as much. One is the post CWC drained players, second is after the auction this year players know that they are good for another three years - they can again catch the eye in IPL2013 for the next autctionSocial, do you reckon its been noticeably worse than previous years?
IMO, It doesnt really matter so long as the drop in skill levels are not comincally bad and the matches are tight. No one reallly comes to see classy cricket at IPL do they? We have the English Summer for that kind of entertainment.
