I wouldn't say Sagan got out sprinted. His wheel tactics today didn't work as the Cofidis lead guy pulled off when he saw Bouhanni on Sagan's wheel, leaving Sagan out front by himself. At that point, any sprinting would just be towing Bouhanni to make the jump at the line. He waited to see what the field would do, and by the time he started his sprint, Colbrelli from Bahrain-Merida moved from the middle of the road across both Sagan's and Bouhanni's lines causing both riders to break their rhythm enough to leave them out of contention. It would had been a different outcome for Sagan and Bouhanni had Colbrelli just held his line.

Good analysis, 100% agree. I would also add that Bora seemed a bit lost in the run in.
