I'm not saying that my view is the best. The thing is that highly doubt elite athletes will function better than they currently are just by increasing protein intake.
Jason Ferrugia wrote he actually has his athletes on similar dietary intakes (high carb, moderate protein, low tomoderate fat) as discussed in that article.
Dave Tate functioned fine even though some of his diet logs showed he ate a diet of 10% protein and 10,000 calories. That would give him 250 grams protein, less than 1 g/lb of bodyweight.
I'm not into the whole protein boatload. But again, just because I'm not into it, doesn't mean that I'm right.
