The old Abbas would have got a heap of wickets on these New Zeland tracks. Unfortunately, Abbas has lost almost all his venom over the last few years and his performances have literally dropped off a cliff.
There's no point drying up the runs if you present no threat of getting a wicket. All you're doing is slowing the game but not actually winning it. In a 5 day game, a batsman who scores at a strike rate of 40 can usually win you a game if he doesn't get out. So by not getting anyone out, or even threatening to get anyone out, Abbas isn't actually helping the team.
There was a time where in county cricket, Abbas was just returning ridiculously good stats. Much like his international career though, he now produces nowhere near those figures in county cricket.
The point is that all signs are showing a steep and terminal decline for Abbas and this looks to me to be the end of the road for him.
I could list a hundred Pakistani players who have gone down this route of terminal decline. I really do not understand why this is so common in Pakistani cricket. One minute a player looks World class. Next minute that same player struggles to hold a bat or struggles to bowl anything of substance. In the current set of players, that is true in the case of Abbas, Naseem, Yasir Shah (showing some signs of getting better), Hassan Ali (yes, he is looking promising again but his drop in performance was extradoniary when he last played for Pakistan), Fakhar Zaman.
There are plenty of examples in the last crop of players too (Ahmed Shehzad, Nasir Jamshed etc etc). How can all of these players perform at exceptional levels for a consistent period of time and then one day, they just suddenly stop performing forever. It's such an intriguing and annoying part of Pakistani cricket and I can't explain it.
