Definitely PSL 'll help PAK players to approach chase better. I give a classic example - what happened in 1st half of KK chase yesterday is typical Pakistan chase - the high target got into the player. Nauman, Simmons, Imad came with a plan to hit everything, resulting lots of dots followed by a cluster of wickets - that was end of it.
What happened in 2nd half is an eye opener, albeit by 2 Englishmen - I am sure PAK players 'll learn few things from that chase. LO games gives lot more time while chasing than it looks. An asking of 7/over on absolute belter for 25 overs sounds daunting - but it's about making up 25 balls, 175 of 150; 1 hit every alternate over & 4/5 singles, these days most team can win from there, PAK 'll lose 90% matches by less than 35 runs.
I am sure, by the end of PSL, PAK's chasing 'll improve.
