Have to praise PAK batting here - with Saim batting, could have saved or even threaten a win here!!! However, bowling choices were atrocious - apart from PAK 1st innings, this track has produced 1000+ runs for 15 wickets at 4+ rate.... not sure what PAK tank was thinking for choosing a military medium bowling line-up with couple of part-time spinners.
Ideally, here PAK attack should have been Naseem, Shaheen, Abbas/Hamza and one specialist spinner who takes ball away from right-handers (SLAO or Right arm Leggi), backed by Aga.
Also, I think ICC needs to amend substitution law - along with concussion, if a player is injured serious enough not to take part further in the game, a similar replacement should be allowed.
Riz gone, but still Aga can save this Test with a 150 here, but PAK tail has to grind it out in middle - SAF won't like to chase over 170 here.
