I know it's pretty early, and Nasrat is still regarded as a prospect, but I think this loss was FAR less stock diminishing than his TKO loss to Drew Dober. Dan Hooker outside of Khabib gave Dustin Poirier his toughest fight at LW in recent years and even almost TKO'ed him in the 2nd round. Hooker's record may not be the prettiest, and yeah he got sparked in his last outing by Chandler, but he's a proven elite at LW with career longevity in this Company not many fighters can say they have. Nasrat was fully expecting a stand up battle, and while he was mostly losing that as well Hooker showed to have the higher Fight IQ and be the overall more well rounded fighter.
In light of losing his Mother(Rest in Peace) and losing, with the Mindset he's displaying, the only place he can go is up. It's a loss that will age very well with time, and he can still improve himself.
