Need adivce on my swing.

Need advice on my swing. I shot some video of my swing last night and found to things I don’t like. 1) Once I get to the top of my back swing my left arm starts to bend too much. Can this be caused by not enough extensor action keeping the left arm straight or by the right wrist cocking instead of bending? 2) The second problem I’m having is feeling the lag in PP3(which I believe is the fat part of my index finger of the right hand pressing against the club shaft) as a swing down into impact. The only way I can get this feeling is if I wrap the index finger of the right hand around the club like John Daly were it looks like a trigger finger. Is this okay to do this?

Thanks
Tim
