Umar's best chance to make the squad (PAK) is as back-up WK, because PAK's reserve WK would struggle to bat at No. 7/8. Sarfraz being Captain, unfit (& over aged for such work load), at some point will need rest at least from keeping, to play as specialist bat/captain - in that case PAK must have to have a back-up WK, who can make the team as batsman. I am sure, this calculation is done at LQ end as well, otherwise they won't have gone with a squad without any regular WK and remember, they had all but one 1st pick in every draft round. Personally, I don't think if he is fit, it'll take much effort to match Sarfraz as WK; to be honest - against spin, right now I am not sure who is better!!!
Maqsood is the cleanest hitter of the game, not only in PAK. I saw him reaching extra cover crowd with a checked drive - that's 85 metres from a top hand flick - you have to go long, long, long back to see such things from a certain West Indian (And, couple from PAK as well).
When you have such players, you have to be ready to accept that most times he'll get out to loose shots, but few times he'll win matches from hopeless situation and set many wins from 50-50 situations. Last night that 80, few years back he made a 123 of 71 or so to knock Punjab out of PAK cup defending 310+ in 41 overs to qualify, another time, he and Fawad scored 170 in 16 overs to chase an asking of ~10, for a distance of 200+ runs against SRL ........ these are not miracles, these are indicative of the capability. But, such players need backing for their aggression - unfortunately for last few years PAK's style had been to praise players for making it difficult to get him out, rather than scoring runs - it's like LBW without offering is better than hold out at long on .... in T20 - so Asad, Azhar & Ahmed played lot more matches than SM.
I wish Multan plays him at 2 or 3 in PSL and give him a full run of 10 matches - Moody is there & I have lots of respect for him. It might happen this time.
Amin, Babar, Maqsood, Sarfraz, Malik, ****, Shadab, Fahim, Amir, Hasan, ***
That's a great T20 side, on potential (Apart from No. 4

)
