Even if you try to compare apple with apple (statistically speaking) you'll see there hasn't been anything horribly wrong (as some cry babies are suggesting). BD has played 13 ODIs with stronger teams under JS so far. If you consider the last 13 ODIs under DW (as the team must have been matured after 4 years with DW before JS joined) against stronger teams (that excludes Ireland, Kenya, Zim etc.) you'll see the following:
| | Avg Score | Runs per Over |
| Last 13 matches with DW | 179
| 4.06 |
| ALL 13 matches with JS | 183
| 4.11 |
Does it show any deterioration in performance? Runs per Over is also suggesting that curbing shots gave us higher run rate under JS!! So "Fatch Fatch" bon koren. Have patience.
