Bowling and fielding aggresively should be the prime objectives for BD. The pitch has nothing to offer except low bounce. We dont know for sure when it will start to talk for spin bowlers. So, bowlers should keep focusing on line and length that does not offer any run.
Early wickets of SA might put BD in trouble. If SA is all out by the 2nd day, will BD be able to bat long enough to have a healthy lead and put SA on pressure?
Historically, BD scores more runs in 2nd innings. But scoring run is not the lone factor that will help bd to fight back in the test match. BD needs to kill time so that SA is constrained with time. At the best case, our bowlers might be able to hunt down SA batsmen cheaply in 2nd innings. But lets not indulge ourselves with this thought.
Again, allowing SA to stay on the crease means more run for them unless BD can persistantly keep bowling and fielding at their best . BD can not concede runs. Eventually, time will pass on and the match will be tight.
This whole observation might sound weirdly defensive. Realistically, BD should aim at drawing the test at best. They will have to out perform the 2nd best team in cricket world within 4 days if they want to win it. I really doubt any miracle in test match. We should try something out of the box. We have nothing to loose after all.
However, I would love to see BD bowlers get them all out in first innings quickly. Then BD batsmen score runs prolifically. Next BD bowlers nail the SA batting order. And we win..........sounds like fairytale???
