Mongoose bat might have made a difference...???

Yesterday CSK suffered a mighty blow from DC. The possible reason would be Hayden not using a mongoose bat or Gilchrist, Symonds or Gibbs not needing a mongoose bat. But I feel mongoose bat might not have made any difference.
As we know, CSK is pathetic in their bowling department, which is not much of an excuse, as they are the successful group compared to other seven (reaching semifinal and final in their last two IPL). They actually reached both with this pathetic bowling department. Except for a forceful weapon named Murali, CSK’s bowlers are a bunch of decent performers, who can’t win any match with their bowling.
So, where was the problem?
I feel the problem laid in the role definition of the batsmen. Vijay, I feel is the main culprit. He has a gun waiting to blaze away the whole of DC on the other end, and yet he tries some stupid shot and gets bowled. He is really good in taking good singles and playing ‘Bevan’ish innings, why, the hell, is he trying to clear the boundary, that too just the third ball he faced in the innings.
Ok, he tried something stupid and he got out, Fine. The next step should be a consolidation act, isn’t it? Instead of sending Raina, Badri would have been a better option, to play that kind of innings. There should be clear strategy, that if Hayden gets out we should send Raina and if Vijay gets out we should send Badri. By this way we always have balance on the pitch, which acts as a consolidation. If this consolidation act gets us to 10th - 12th over with 2 wickets down and some 7-8 runs per over, we have chance of completing any chase, with the firepower of our lower middle order. This, I feel, would help CSK. But still there are always people who know things better than us. CSK ku whistle podu  …!!!
