Bangladesh can no longer be considered a minnow, they have proven several times they can mix it with the best and they will be at least competitive in the super 8's
On the other hand, Ireland may not be as competitive, but if other teams begin to assume that they will whip them and don't actually try, then Ireland could pull an upset. However, if you replay that Ireland, Pakistan game 99 times, I reckon Pakistan would of won at least 98 times, unless the match was fixed of course.
I have no problems with the inclusion of minnows in this world cup, but the fixturing system of this world cup means that the Minnows have to only pull off one flukish, D/L Method upset to advance to the super 8 stage, which is ridiculous. I prefered the old system whereby a couple of wins were required in the group stage, minnows would have to prove more than once, that they are the real deal. Kenya did get to the semi's of the world cup last time though, but courtesy of some D/L wins.
I fear for Ireland during the super 8's, and don't want to see them get smashed, so I hope they can be competitve, since they have qualified for the next phase of the competition.
