That's what we are led to believe but it's simply not true. In years gone by the quality has been better with guys like Nabi, Malan, Jordan, ABdV, etc but it's really tailed off to the point where blokes like Livingstone, Fletcher and Hales are considered stars.
Most of the real big names like Kohli, Williamson, Stokes, are tied up with test cricket but even still if you have a cursory glance at the ICC T20 player rankings, the BBL has:
- 1 of the top 20 ranked all rounders
- 3 of the top 20 ranked batsmen
- 5 of the top 20 ranked bowlers
It's the reason guys that dominate BBL like Sams and Stoinis are exposed in t20i games and very few Aussies are starters for IPL franchises. The leap in the standard is massive and the likes of Khan, Mujeeb, Maxwell must get a serious laugh out of it.
