In kinda hesitate to maybe push his second prime up to 2011... sure
-he lost to Jones, but he's the (steroid included list) GOAT, and after that flying knee he really wasn't himself in that bout...
-6 months later he avenged his loss to Forrest Griffin in brutal fashion, took less than 2 min. And that was Griffin just after beating Tito & Rich Franklin, and then beating Tito again after the Rua bout. It's not like he was on some insane losing spree...
-1 months later he took part in one of the best brawls ever against Hendo [the official UFC FOTY], which IMO should have been a draw (Hendo 10-9 for the first 3 rounds, then 10-9 and 10-8 for Shogun in the final 2; but the UFC judges almost never give 10-8 rounds, or draws).
Henderson was just fresh of a win over the HW GOAT himself, Fedor, and 2 wins before that against Strikeforce champion Rafael
Feijão Calvacante & a rematch against the always game Babalu Sobral, who had just beaten Robbie Lawler.
It was the first time Mauricio wasn't able to avenge one of Murilo's losses

even if that Hendo/Ninja decision was bullshit; I'd argue that this one time, Ninja did better than Shogun when facing the same opponent.
(once again, this makes me miss good old
Ninja>Shogun , he wasn't very popular as a sherdogger but his takes were never boring ^^)
The next bout, in which Shogun struggled to put Vera away was the one that really made me realize that his second prime was over.

Don't get me wrong, Shogun won all 3 rounds before TKOing Brandon is the 4th, and Vera is a tough veteran, no question about that, he's bigger and taller than Rua (KO'd Frank Mir at HW back in the days).
(and IMO, should have gotten a draw against Randy Couture instead of a unanimous decision loss...)
But in my head, the Shogun who blasted Chuck Liddell and Machida twice, who was so quick on his feet, and upped his boxing skills to compensate for the ban of soccer kicks/stomps in the UFC (which sucked for Chute Boxe guys, Mauricio in particular who was the best & most technical at using these types of strikes) would have make quick work of
The Truth
TL;DR: the first Hendo 5 rounds war is one of the factors that "broke" Shogun for good. And that was in 2011. Holy shit, that decade flew by...
Rua took so much damage in this one, it was crazy how he came back...

I had never wished that much for a 6th round ^^ what a crazy, bloody, Rocky-like comeback...
Like in the old days, if a fight oo close to judge, let them go 1 more round... As long as Ken Shamrock isn't in attendance.
