I will only advice you to not to get too excited after seeing the toss and place the bet on the team batting second. What if the team batting first is able to make 200+ runs making it extremely difficult to chase this in the second innings. Also chasing a 170 runs wont be easy as there will be the pressure of the final.
And how many times in this tournament we have seen a score in excess of 200? It is not easy as it sounds. Especially in the UAE, overs 7-15 have proven to be very difficult for scoring. I can't remember a single one out of the 16 teams performing well with the bat on a consistent basis during this phase. It should not happen ideally, but in the UAE, teams batting second are having an unfair advantage. And this happened during both the semi-final matches. So toss is very important for the final and the team winning it will have a greater chance of lifting the trophy.
I think it was done by India once in the tournament that they scored in excess of 200 runs in the first innings. I do not remember any other match where any team scored 200+ runs. But my wording was that a score of 170-200 could be a competitive score if scored in the final.
Also doesn't the teams playing second face the same difficulty in batting from 7 - 15 overs ?
