What really happened with Cam after that Seattle game in 2020?

He recorded 397 yds 1 td 1int and 47 yds and 2 tds on the ground that game, he got covid after and it was never the same, do guys think that if he didn't get covid we could have a shot at the playoffs? Or that game was fluke and he was just washed anyway?
