a couple things bother me about his form. as mentioned earlier, he's hitting against a machine so he should not have timing issues.
aside from that, it looks like the guy has a closed stance prep but the opens up a bit before actually hitting the ball. he'd probably be well served to simply go with an open stance and keep most of the swing the same.
the other thing that bothers me is the lack of consistency in how he's finishing his swing. racquet points all over the place, sometimes finishing over the shoulder, sometimes at the elbow, etc. assuming it's a consistent feed, i would look to have a more consistent swing.
he has some good ones in there mixed with some not as good ones. in my experience, though, a guy who plays a decent amount will usually have a decent forehand anyways. if you really want to help him with scholarships and such, i'm betting there are weaker parts of his game to address instead of shoring up what i'm assuming is one of his stronger points.
