weightlifting coach talked me off the ledge

I listened to a pod cast by Mark Rippetoe a little over a month ago. He claimed the reason Americans are so poor at Olympic style weightlifting is that they don't do enough deadlifts. He said that American coaches are making a mistake by adopting the European model of weightlifting where they have thier athletes do tons of pulls but very few deadlifts. He was essentially saying anyone training like that isn't strong enough to lift the weights they are capable of. Since listening to that podcast I've been obsessing about doing more deadlifts. I've been contemplating sneaking more deadlifts into my training program. Vernon Smith, one of my two weightlifting coaches, talked me out of it. He said I shouldn't mess with coach Joaquin Chavez training programs. He said that my squat and weightlifting numbers show that I have more than enough strength. That it's my form that's holding me back from lifting more weight.
