I subscribe to the notion of picking your best bowling attack. Which may entail picking a lesser bowler, yet one who complements the bowling attack such that the total is greater than the sum of it's parts. We're not picking the best batsmen + best bowlers (a computer could do that), but the best team combo.Yes, this is similar to the side I was advocating. Pick your four best bowlers. This side can beat the 90s/2000s.
Same with the opening batsmen combo. Greenidge or B.Richards complements Gavaskar, but Boycott does not.
Hence, I'd replace Hadlee with Qadir - a specialist LBG to complement Viv OB and Border SLA spin bowling alongside the pace attack.
There's very little Hadlee can bring to the bowling table that Marshall, Lillee and Imran cannot, but Qadir can contribute much more.
