Nadal was outplaying Djokovic, up a set and was never challenged on serve and then from 3-3 in the second he couldn't hit a first serve anymore. Yes, that's crumbling.
You're either lying or delusional, or both. I give Rafa credit when he outplays Nole, but the truth is, that only happens on clay. On hard courts, Rafael was never able to blow Nole off the court. On the other hand, Djokovic has blown Nadal off the court on several occasions.
IW and Miami matches your talk about were pretty even sided until the final set, where djokovic outlasted nadal, mentally and physically.
You can say what you want, but on hardcourts, Nole is on a different level, just like nadal is on clay.
