You will be amazed to see the big names like Morgan, adil rashid, hafeez, bravo taking part in this league. Missing big players are because they are busy in bilateral series NZ-INDIA, WI-SL, Pak-Bangladesh. I m sure they are paying good that's why big players are seen here. IMO second one after IPL is BIG bash of Australia. This T10 is mini ipl as organiser is of indian origin.
T10 is not my favorite format, but still I watched a few matches because a lot of the well known players are participating. And UAE doesn't have any natives playing cricket, so there is no restriction on overseas players.
