Re: Deadlift form
Sadly being a college athlete does not equate to proficiency at basic strength exercises. In fact most college athletes have very poor if any strength program and are good because of natural talent not their training. I played Div-I water polo and while our team swam a lot for conditioning and were reasonably fast, in the weight room they were rather deficient. Water sports in particular tend to have a lot of weaknesses that do not come through in the pool.
So you are probably right, she has very large weaknesses. If you want to improve her preformance I would start with a basic strength program so that she can develop the muscle that she lacks and be able to do decently heavy DL, Squats, and Presses.
