I do think that's a fair criticism of KAT since he was that way before gobert even got there. But like, where's the criticism of gobert for the opposite? He doesn't stretch the floor and is good in other ways, why is KAT the one taking the heat all the time? It's fair to say KAT has weaknesses, but so does every other non-stretch big.
Like earlier charon said "The guys who are supposed to be scoring aren't" but I don't think that means gobert should be excused for having a very glaring flaw in his game (that he's never been a scorer.) The object of the game is to score, just cause you aren't good at it doesn't mean you don't get blame if you don't do it imo. If we're excusing players for flaws they've always had, then it doesn't make sense to go after KAT for not being a traditional big man, while not going after gobert for not being a stretch big man. Just make it equal.
If we're concerned that gobert would not get the same trade value that KAT would, to me that speaks volumes about who the more valuable player is.
