Bangladesh needs to change their captain

[Alien]

Bangladesh's performance can be explained by the F(x) = Sinx

Start from 0 and get belted for a while and then when you have that "nothing to loose" attitude, they go and hammer some big guns like Australia or India. Once they are on top, they get all nervous and then they get belted back to 0 sometimes to -1 from where they rise again. Just like a sine curve, it goes up and down and been like that for last couple of years.

What we need a performance of y = x where it will go up and up to infinity without ever going down.
