I think it speaks more to the lack of depth in the upper weight divisions.
Poatan is now at LHW
Driccus already beat #3 Whittaker and #1 Strickland.
#5 Cannonier is coming off a TKO loss
#6 Vettori is injured and #8 Costa is out of the picture
The 'on the way up' guys in the division right now are #7 Allen and #4 Imavov, who fight each other next month. That will produce the next contender.
Allen needed to put Curtis away and make a big statement to stir things up, but he eeked out a split decision. Imavov is on a two fight win streak, I think its good match making to put these two together.
In this landscape, Izzy gets a title shot he doesn't really deserve by good timing and the UFC paying peanuts. Upper weight divisions have shallow roster depth because the pay is so atrocious.
