I think a dedicated Team A Taiwan with a naturalized player can potentially upset a rebuilding China, Team B Japan, or even become favorites/competitive against a D/C team from Australia. You can call me crazy, but they did beat Guam. Although Guam was not in their best form, I considered them a team B of Guam, but they did still have Tai Wesley and Galloway.
I was one of the many people who counted them out against Guam, but their performances changed my view.
Also, it is important to acknowledge that the Taiwan lineup we saw against Guam was not their most capable lineup.
Taiwan has a problem with their pro league situation right now. Imagine if there were 3 other NBLs in Australia. That is the situation Taiwan is having right now, which is hindering their ability to field the best lineup.
The one we recently saw was probably like a B team from Taiwan as well, and like Guam, they did not have all of their key players.
Yes, they did get outclassed by Japan and China in the ACQ, but their roster at that time was not as good as the roster they fielded against Guam. In the ACQ, it was more like their C team, which was why I also counted them out against Guam because I thought they were sending the same roster for their final games.
