we have three specialist batsmen who are candidates for no 8 batsmen
1. mahmudullah: introducer of the thoery, was very successful at no 8
2. naeem: when mahmudullah got a promotion, naeem got the chance here. did well in a partnership with shakib against england in a game where after a good partnership which was looking to be a match saving was blown when shakib tried to hit a six of the bowling of tradewell. naeem contributed well in that game at no 8 and had few other decent innings at that position.
3. nasir: the latset sensation whi has finished well in some ODI innings for BD is now favourite for that specialist batsman at no 8 slot.
4. just as i was writing i found a Darkhorse for the position. Sharapova Rajib, who has played well in same nightwatchman innings for BD can be a potential dark horse for this no 8 position and thus demote naeem or nasir to no 9 and thus explore the opportunity of having a specialist batsmen at no 9
