Appreciate the work you put in here... but if we are going to call Martin and Powell proven players then we can go ahead and loop in Svi and Niang. If the roster is ever close to 100% in Dallas then I agree they have a better overall roster... but their hole at PG is still a huge issue. I doubt AD plays more than 10 more games as a Maverick this season one way or another. Lively can't stay on the floor. I think PJ is also dinged up but not sure rn.
For us to benefit (and according to your post properly scar our young players for life) they will need to actually play. More Taylor/Cody/Brice minutes is 100% what I am advocating for and then the losing will come... or they will be too good to lose but if you are relying on your future contributors for that it isn't a bad thing necessarily.
We have played 5 "tank" or horrible teams... Dallas has played 9. Yet they still amassed a worse record. They are absolutely in the conversation with all the teams you named... and us.
