John Wall is a phenomenal guard but he isn’t the type to drag a team into the playoffs on his own.
At the same time, not every team can be a contender for the NBA title, it’s usually only 4–5 teams at best. This season it’s like 3 (and that’s being nice to the spurs).
I don’t think Pop considers this a lost season even though a LMA-Kawhi duo probably won’t go farther than WCF. Once you have top talent it’s tough to find it again. Every lotto pick takes years to groom and become good enough to push the needle on their own. If I’m the Wiz GM I keep trying unless Wall says he wants out.
