I belive KKR could have easily chased this target especially when they knew they had russel as finisher . All that KKR had to do was to keep wickets in hand and score 70-80 in 10 overs with loosing not more than 2 wickets.
Sending russel on 7th was the most absurd decision by KKR especially when chasing such huge total . Again i say KKR is not using his full potential. Sending him below 4 or 5 wont make any difference for KKR at all.
