I dont think going back to Gautam Gambhir is the right way, frankly. Has he gone out of his comfort zone to county or other countries and shown that he can play high quality fast bowling in tough conditions? These Duleep trophy scores don't make much impact especially when you know the guy inside out and you are confident that these scores cannot most likely be replicated by him in the real games for India. Also the issue with Gambhir is his attitude, which is downright negative.
For Gambhir, I would instead stick to Dhawan and have Dhawan as the reserve third opener.
I'm in agreement about his attitude. I think I mentioned it earlier also. It can really bring a team down. Also, Gambhir and Kohli are like a match and gun powder, so if there is disagreement, they can bring the whole house down, although Kohli has shown tremendous maturity in his career so far.
As far as his recall in comparison to Dhawan goes? I don't think Gambhir is any worse. Like I said before, he is better than Dhawan on every level. I rather pick a chap who can get a bit hot under the collar but cares about his wicket rather than a moustache twirling, thigh slapping chap who can't care less how he gets out every test innings.
I know Gambhir is a very debatable choice, but let's look at things in perspective-
1) There is no doubt that Vijay and Rahul start the season, so unless one gets injured Gambhir is unlikely to play.
2) In the event that there is an injury, we're only looking for a short-medium term replacement. Personally, I think on those turning tracks an opener that can play spin in his 2 am sleep is like gold dust. Gambhir also has a lot to prove and must be very motivated and just like his personality and attitude is outright pukish, sometimes it can spur an individual to great things. At least, in the worst cases of worst, he will be at Dhawan's level.
3) If India go abroad next year, we can start bedding in a younger reserve opener. Like I mentioned earlier, this is a stop gap solution left to fate. If Gambhir can prove himself, good, otherwise farewell.
But why am I continuing this rant? Dhawan is already in the squad.
