With only 4 overs per bowler, I have always held that you don't need more than 5 full bowlers. Any additional cover can come from a batsman who can bowl i.e. not a full bowler. And the 5 full bowlers includes one genuine all-rounder of about Hardik Pandya class. This allows you to have deep batting down to number 7 (followed by 4 bowler first batters and if you are lucky you would have an Axar level batsman in the bottom 4).
What do others think? Why is there a trend especially among Indian selectors to play 6 full bowlers? What are the arguments?
Well they actually played 4 specialist bowlers in the recent tour vs WestIndies, Axar and Pandya are considered all rounders ..
It's very dangerous to go in with just 5 bowlers cause if someone gets injured you are relying on a part timer to get your overs in,
Also teams can line you up if you only have 5 bowlers cause your plans aren't going to change that much ..
T20 is not so much about quality, more about strategy ..You can beat a team with much better individuals with guys that are specialists in boundary hitting , guys who know how to bowl at the death , flexible batting order ..That kinda stuff ..
Take the West Indies for example they won 2 T20 World Cups packing their sides with batting and bowling all rounders , think Pollard , Bravo , Russell , Sammy, Carlos Braithwaite, then they also had batsman who were a bit better than your average batsman who bowls a bit like Chris Gayle ..
The last T20 WC you had England winning it , Stokes and Ali were batting in the top 7 but also bowling their overs throughout the tournament and Livingstone was also in the top 7 and he was bowling aswell if need be ..
Having a rigid formula in t20 doesn't often work .
