I do not know what does under or over rated means..... and what are the basis of some players being tagged as under or over rated here.....

If under or over rated implies to the media hype..... yes there are some players who are much hyped especially some Indian youngsters and English cricketers.... Thats simply beacuse they have a strong media presence in their country... It would happen everywhere...

In my view there are really some players who are unlucky like Stuart McGill who was over shadowed by All time great Shane Warne.... Michael Vaughan is a great test (BUT NOT IN ODI)batsman but I do not consider him under rated as no any english cricket fans or media will under rate him..... In ODI I think Laxman was underrated... Jaysurya was underrated as a bowler in both formats.... Akram was underrated as batsman....

Regarding overrating of players.. I can genuinely see some Indian youngsters being over rated... there are a lot of them in One Day team especially....but I never think Sachin/Sourabh/Dravid/Shewag  being overrated as test or ODI players... they deserve the credit.....  Dhoni isnt still a test great but not an overrated one day player or leader... Sohaib Akhtar is a bit over rated given the number of matches he have played but he is still a fantastic player when physically and mentally fit....
