What exactly won Casp11

Hi there,
I'm a little confused. In the paper "Template-based protein structure prediction in CASP11 and retrospect of I-TASSER in the last decade" a complex pipeline is stated in the flowchart of the template based modeling (TBM) by “Zhang-Server” in CASP11. It includes I-TASSER, LOMETS, FG-MD,QUARK, Threadom,... But on the I-TASSER Webpage it is stated "I-TASSER (as 'Zhang-Server') was ranked as the No 1 server for protein structure prediction in recent community-wide CASP7, CASP8, CASP9, CASP10, and CASP11 experiments", which sounds that olny I-TASSER was used to produce the Casp-Winning results.

What is right? Did I-TASSER alone produce the Nr.1-result for Casp11 or the pipeline described in the paper?

Thank you.
