If Yadav is someone's captain, the replacement would take over that role if switched. That person could then decide whether it's more beneficial to keep Yadav, or take the replacement.
In my case I have Gambhir as captain, who will be on -28 points after last night's game is scored. If he was rested/dropped and I could sub him out, I would then get Jadeja and 244 points + double what he scored last night.. I don't think that's fair.
then thats your good prediction. You basically picked Jadeja as reserve because you thought there was no better replacement than him as WI lacks quality batsman and jadeja bowls also.
Gambhir is a class and consistent player and its unfortunate that he has not scored.
When i picked Rohit as my captain, then i took the huge risk as he bats at 5 and if gambhir or sehwag would have fired then he might have not got chance to bat only.
You also have some good points and i think i also some valid points.
This Fantasy cricket is awesome but i think it still lacks some feature and due to missing feature this issue has been created.
1. There should be value for each player.
2. Transfer System. (eg: 20 transfers for series, so manager can change player for each match.)
----------
Doesn't matter if Yadav gets replaced or not, but Aayush's team has done enough to be on one number 1 spot.
you are second. Things can change easily if India top-orders fire and specially gambhir.
i have a feeling that ton from gambhir is just around the corner. His one of those player who scores runs when people start raising fingers on him or opposition bowler says something to him.
Can we have Sylvester's say on this matter.
But another century by Kohli can certainly do it for me! also he needs to bowl and take some wickets as well to make it possible
