Haha, funny you should mention him now because
I did a few months ago and then
you said you'd not heard of him.
Definitely something to work with (reminds me quite a bit of Junaid the first time I saw him) but there are quite a few little technical things you could change about that action to increase his pace and accuracy.
Firstly his run up seems to consist of running 15 metres at the same pace and then bowling; I'd look at trying to make that run up a little more explosive even if he cut it down a little bit. You don't want to be accelerating as you enter your action because then you lose control over your movements but he doesn't accelerate much at all after the first few steps so a lot of it is wasted IMO. Hard to make any real judgements on this based just on his wicket balls though.
The most noticeable about his delivery is his front arm. You can see he's come from the school of snapping it down fast to generate pace but, as with a lot of young bowlers who get taught that, he's missing the point of having a front arm at all and that's to align your action and give you accuracy, symmetry and a good wrist position. He needs to get that arm up a lot higher before he snaps it down, and that's a relatively easy thing to fix. I bet if he actually watched this footage (lets hope he does..) he'd think "wow, is my front arm really that low?!".
Another thing I noticed was this:
He's got a bit of a teenage Jimmy Anderson going on (although not as exaggerated - Anderson looked sideways) where he's not really looking at where he's bowling. He's also not making full use of his height there as, while he's got his arm in a good spot and he's braced his front leg, he's crouching a little bit ala Nathan Rimmington. He'd do well to work on keeping that head a bit more upright and down the wicket if possible, although a lot of bowlers just lose their actions completely when they do this; it's not an easy thing to change.
The positives are that he completes his action well, gets through the crease nicely, looks to have a very natural angle away from the RHB and, so far, takes lots of wickets and a tiny average. What he sends down looks decent enough in that video but it's basically impossible to make any judgements on that from a few balls.
Needs work, but at 23 with the record he's got, he's definitely a potential international bowler.
