Recent series against Australia showed the positivity of IPL. Gill's pull shot against Strac, his cut against Cummins over third man. Debutant Washington Sunder hooking against no 1 bowler Cummins are couple of good examples.
The way in which all the debutants played without fear is because of the exposure they get during the IPL, sharing the dressing room with International players and learning from them and that has helped each and every player greatly.
As Gavaskar recently said that future looks good for Indian cricket but don't allow this fame to get into their head, it might destroy everything.
Vinod Kambli comes to mind
. All the players are dedicated and if they control their urges and work hard on their skills they will don the jersey for a long time, if not other talents will come along and replace them.
