Need help fixing friend's swing

[DCgolf]

I have been trying to help a buddy of mine with his swing. He swings really good one day and really bad the next. Mostly occurs with his longer clubs. He is struggling with a low pull right now and the occasional chunk. He is obviously standing up in his downswing. Any suggestions and tips would be greatly appreciated.

Id like to see a grip close up; im guessing it's weak. in a more general sense this swing is too locked up in terms of body and arms (stiff if you will) I'd have him hit a lot of balls with his feet together for a while to give him some sense of a free-er arm swing. And try getting him to keep the club face looking at the ball longer on the takeaway to avoid twisting it open as much. good luck

Thanks for the input. I agree on him being too stiff and locked up. Definitley needs to keep club face looking at ball longer.
