If indeed IPL is fixed then we would have seen all teams winning the trophy at least once. As Nikhil pointed out, RCB would have won. MI and CSK will not be where they are now.
In this video after coin spinning stops refree said it's heads & he poke his finger on Raina's side CSK won the toss then refree was in too hurry like he was did some crime
I viewed the video multiple times and nothing looked fishy to me. The match referee didn't take the coin while it was spinning. Raina called heads and the match referee said it's heads and that CSK wins the toss
