Bloody Amol Muzumder is now a specialist commentator on Neo, and all they can offer for Yuvi's failure is criticising his technique (without specifying WHAT part) and showing repeated replays of Yuvi taking eyes off the ball and getting hit...and then hinting that it might be due to Yuvi's lack of willingness to guts it out. If he hadn't gutsed it out, Sachin would have retired without World cup.
Yuvraj Singh has all the attacking shots against all types of bowling. Sadly, you need ALL the shots in Tests including defensive ones..even Viru needs them in Tests even if ever so fleetingly.
I believe all the support staff, coach and senior players have failed to drill this into Yuvraj in 11 yrs and thus let India lose its most talented young player to lack of evolution. Which is why I am seriously worried about succession after Big Five.
Before you give them top class support, the young cricketers need to be trained to use & imbibe that support. Those 5 came with that mindset..but who's teaching those whose minds are not as focussed?
