If you think he is similar to Talha, then you have absolutely no clue on fast bowling.
You provide better analysis on batsmen, but it is better if you keep mum when talking about bowling.
His issue right now is his gun barrel straight run up which is not allowing him to complete his action.
He needs an angular approach that can get him into his side on load up much better. This way, you wont see his bowling arm ending up between his legs like it is right now. It will end up on his left; an indication of a completed action.
His wide of the crease release means that he is working against the angle with his side on action, and hence everything is being compromised; pace, bounce, swing. In turn, the outswing that he is aiming for, is not occuring from off stump, but rather from 5th or 6th stump, which means the batsmen dont even have to play the deliveries.
Had Waqar been worth his salt, this issue would have been fixed by now as I pointed it out right in his first spell in the 1st test. He himself was a side on bowler, who had an angular approach, and delivered from closer of the stumps. If he cant even rectify this, it just showcases how incapable he is as a bowling coach.
