Here are some stats to ponder over:
Since 2007 WC:
BD has broken 250 only 13 times.
300 was broken 3 times (all wins) vs. ZIM (2) and UAE
270-300 accounted for 5 times (2 wins vs. WI & IRE and 3 losses to IND (2) and PAK)
250-270 accounted for 5 times (all losses including one to ZIM)
Only 4 matches have been won by chasing with a 6.00 RPO or better. 3 of them are against ZIM and one against SL (all in 2009)
It has really been our bowling that has kept us in or won us matches in most cases in the past few years.
Leaving out ZIM and WI (due to them not fielding a full strength team), our major wins since the 2007 WC include
1 vs. SL
1 vs. ENG and
5 vs. NZ
For our group:
Last win vs. IND : 2007 WC
Last win vs. SA : 2007 WC
Last win vs. ENG : 2010
Last win vs. WI : 2009 / Never if you consider full strength teams
Last win vs. IRE : 2010
Last win vs. NED : Never
Follow you I will but you have to give me something to look forward to as well.
