Don't just go by averages- they are just results of pace bowlers not doing anything of note and spinners bowling majority of overs and ending up with most number of wickets.For a newbie from a SENA country, it definitely is. Both him & Hartley did pretty well. On hindsight it was great that Leach got injured, don’t think he would have done well in India.
Hartley did better than Shoiab as he actually won a test match at Hyd - again more to do with Indian batters being stupid but still credit where due.
Bashir has been just bowling the same stuff over and over again. His shortcomings were evident at Dharamsala where Kuldeep and Ashwin ran through England batters and got huge turn while he was just bowling largely harmless innocuous stuff for most of the time. Had Jaiswal not being absolutely irresponsible and played that Bazball shot, Bashir's numbers would have looked far far worse. Same goes for stupid shots like the one Sarfaraz played.
I watched every ball in this series and I think Rehan looked arguably the best out of the 3 upside wise. However Rehan being an inexperienced wrist spinner was inconsistent and served up long hops periodically. Instead of backing him, Stokes discarded him. He also used Rehan quite badly - bringing him as late as 40th over.
