Sometimes you see players who work very very hard but are not naturally talented (Shiv, Gooch) and sometimes you see players who have an abundance of talent yet don't work hard. (U Akmal, Gower was like that too even though he achieved way more than UA has)
Razzaq was the latter. A guy of his abilities should've retired with stats like Botham, 300 test wickets and 4000+ test runs yet he got lazy felt entitled to be in the team so let fitness go (sound familiar?), began throwing tantrums, and before you know it it was all over. Story of so many of our players.
Was a gun loi finisher with bat and ball. This game with the bat, and the game vs Sri Lanka he tied with the ball singlehandedly when they were cruising to chase an average 230 I think it was.
That's why truly ATG players are ATG, you need a certain mindset to blend talent with hard work and dedication. A growth based mindset.
