I'd generally agree, if it weren't for the fact that
A) CJ didn't get covid until a few weeks ago whereas his poor play has been a season long phenomenon and
B) He was really bad in the playoffs last season too
Unless you mean when he went into covid protocols last year, but if you're arguing that his poor play today is a result of him getting covid in March then I think he has serious issues that should concern us long term. And if he's ''working his way back to game shape'' you should expect his play to be getting better rather than worse, and it hasn't, generally speaking.
In reality, I don't think CJ is doomed. I'm totally happy to believe he'll be better later in the season and that he's just going through the roughest patch of his career - sometimes that does happen, and yeah, it's possible multiple bouts of corona have been catalysts for that poor play. But that doesn't mean it's not concerning for the on-court product that our highest paid player who insists on being taken seriously as a lead guard has been dreadful and that many games are being won in spite of him right now.
