if you analyze the batting of Russel and Narine, they need ball coming on to bat nicely.. on slow and low pitches, they generally struggle to time/ hit the ball. even if indian spinner had bowled against them on slow and spinning track of UAE, those batsmen would have struggled. You are talking as if Pak bowlers bowled yorker after yorker to them or beat them with 150Kmph fast bowling.
top bowlers you had in PSL are same old Wahab, Sami, and other few unknowns.
these Wahab and Sami are big international failures.
IMHO batsmen in the PSL are very average, you dont have to bowl yorker or very good ball to contain them.. even good length balls are good enough against those average batsmen in death overs. Once you take first 4 wickets, teams just give up. thats why we saw 150+ being winning score. also most of the teams are not good as chasing. they struggled even to chase run a ball scores with very short boundary. there is a big play ground between the boundary line and fence where spectators are.
there is a big talent gap, especially batting talent between two leagues.
