The first priority in an ODI strategy is figuring out how to take 10 wickets, especially during the middle overs. In these conditions, having two quality spinners is essential, regardless of their batting ability—the combination should be built around that. If you have a great all rounder, that’s amazing, but if not, then you need to make some other compromises.
For example, one option was to drop a pacer and play two spinners. If three pacers are a must, an all-rounder like Jamal could have replaced Khushdil as the third pacer, allowing room for a specialist spinner instead of an extra pacer.
