Justin proved this tournament that he can play solid, be clutch, and win against the top players in world. I watched nearly every one of his streaming matched in singles and doubles and wanted him to crush it every time. But...he also makes more mistakes than the top players in the world that's why he lost in the last 32. At the top echelon of pool, all are capable of playing spectacular offense, but the average amount of mistakes is the overall difference between a world champion and one that isn't. Being a "best" after the break doesn't matter if your mental game causes you to miss shots that you should be making and at his age, he probably has passed his prime both mentally and physically.
He would definitely be a strong addition to the Mosconi team assuming he gets solid experience in this years WNT events against potential opponents. And regarding being "top in the world after the break" is a given since he may be like an 800 Fargo after this tournament because that is within the Top 100 pool players in the world. That is literally better than pretty much every other pool player in the world. If the context is saying he is in the elite top 10 or 20, I would probably argue against that as there are a significant amount of players from the top 100 Fargo that I would put ahead of him for cue ball positioning.
