I really wanna join in on the Shogun circle jerk, but I am really nervous about power/chin disparity.
Smith doesn't have the best hit list, but he has been pretty consistent at landing the power shot outside of the Santos fight where he was badly outclassed. He is long, athletic, and creative at landing big knees and elbows which Shogun will struggle to survive after eating.
In a 5 round fight, you are basically betting on Shogun landing the first kill shot. Which is certainly possible, but how much power does he have left? It took 3 rounds of consistently tagging Villante to finish him, and even though he rocked Corey Anderson a couple of times he couldn't get the finish.
My biggest concern is Smith moving up to 205 will be just enough of a boost to his chin to make a quick KO hard for Shogun. He just isn't on the same power level as Santos who was murking everybody leading up to that fight. And even Villante + old Little Nog wobbled him a bit early-- if that's a big shot from Smith he is going to be more than wobbled.
I'd really love to see Shogun come out and destroy Smith. But I have a bad feeling he is going to be outlanding him with significantly less harmful strikes, and at +190 there's not quite enough upside to justify the risk
