In December 2019, Colby lost to Kamaru Usman in the fifth round of their title fight, via TKO.
In September 2020, approximately nine months after his title fight loss, Colby fought the previous champion Tyron Woodley (then #5) and defeated him via TKO.
In February 2021, approximately five months after Colby fought Tyron Woodley, he moved from the #2 ranked WW to the #1 ranked WW following the defeat of Gilbert Burns defeat at UFC 258.
In April 2021, approximately two months after Colby became the #1 ranked WW, Dana White confirmed at the UFC 261 post fight press conference that Colby would be Kamaru Usmans next opponent.
Since it is repeated now as fact, erroneously, that Colby has been "inactive"; more-so than the other WW contenders supposedly.
Tell me during what period in the timeline above Colby should have fought, who he should have fought that he did not, and why fighting them would have advanced his position in the UFC.
There is nothing abnormal about Colbys activity post title fight loss.
Colby has been more active since he lost to Kamaru Usman than other WW contenders such as: Michael Chiesa, Stephen Thomson, Leon Edwards etc.
You can not care for Colby the person, while still being intellectually honest enough to admit he has been as active as he needed to be to regain his position as the number one ranked contender; and the next title challenger according to Dana White.
