This win only reflects on Khabib as a coach.
Khabib isn’t Islam and Islam set up with striking and went to the ground for the finish on a rocked Charles. Charles needed to be rocked first, lesser chance of this with Khabib. Charles striking is tricky and it could have easily gave Khabib issues or Khabib would have got him down and kept him down etc.
Islam is now 11-0 streak as a LW and Khabib was 11-0 (missed weight and had 2 CW fights)
1 more win and he ties Tony 12-0 streak and after that 2 more wins ties the title defense record. Islam is in a strong position to surpass them all. Charles is a better win than Iaquinta, McGregor, Dustin and Justin at this point. I imagine his 4 defenses will be better competition or equal to Dustin / Justin.
Islam is building his own legacy not giving Khabib make believe wins or validating him. You can have a loss on your record and still build the best LW resume and title run in the history of the UFC.
Islam 15-0 LW run and 4 title defenses > Khabib’s 11-0 LW run and 3 defenses
Islam has more LW fights career wise
Islam 23 LW fights CW 1 time
Khabib 16 LW 13 WW/CW
