CP3 despite conventional wisdom has been very good when the team has needed him to step up in the playoffs. Despite losing in 6 games to the Bucks, he averaged 22/3/8 on 55/52/75 in the finals despite playing through an injury.
Devin Booker who was the first option averaged 28/3/4 on 54% TS.
He missed the first two games of the WCF with Covid and he was clearly affected by it for at least the next two or three games. We saw guys take a while to recover from the affects of Covid after the fact, so I don’t think it’s unfair to say he was playing through Covid in the Finals. You don’t have to be contagious to still suffer its affects.
