I would say it's more the other way around in T20. See, the thing about T20 cricket is you build pressure by bowling economical overs and someone (a wickettaker) can bring about a wicket for your team. T20 cricket is such a format that you can be 5 down in the tenth over and you can still win the game. The key to do well in t20 is to build pressure.Wickets > Economy - It could be cricket in our backyard. It's always better to have a WK taking bowler.
