I think Tamim and Shaks stats link up. The only time BD win is rest of the players (other than Shakib) perform. So when Tamim performs and other players perform we will most likely put up a good score. If everyone gets out then Shakib is left to score the runs therefore Shakib has an inflated average on a losing cause.
