I had a feeling that might happen to Fedor. Congrats to Werdum. Now someone please buy him a T-Shirt that fits.
Fedor tried to spin out of the triangle like he did when he fought Minotauro. The diference is Werdum had a tighter traingle and there was no sweat involved. Notice Werdum did an excellent job of denying Fedor his posture.Great submission.
The other big difference between this fight and Fedor's fight with Minotauro is the cage vs the ring. You can see at one point, Fedor tries to circle out of the triangle, but the cage forces back towards Werdum's guard.
