you've gone thru a lot of work to list 2 options for Portland...it seems
and what's clear, or at least seems to be clear, from your list is that the Blazers need a player as good as Dame, and maybe a player better. But there is not player anywhere close to as hood as Dame on the roster. Ant-Grant-Nurkic are at a level about 3 tiers below Dame. So they aren't part of the equation or formula
so the issue is that Portland needs to land a player as good as, or better than Dame, and who is almost certainly a wing. But I have yet to see one of you guys who are incessantly saying to trade Dame explain how trading away a top 10 player directly leads to landing two top-10 players; or a top-5 player and a top-20 player. There's no formula for that in trading Dame that is demonstrably better than the one in keeping Dame. In fact, any honest application of logic would say that if a championship depends on having an A+B, it's better to have the B and be looking for the A, than to have a couple of D's and a couple of F's, and a bunch of K's and praying to land both that A+B. Keeping Dame at least keeps Portland around 45-50% there while trading him leaves the Blazer 0% there
in other words, what is the actual benefit of trading Dame if a championship in the next 3-4 years is the goal? What is the championship payoff?
what team actually traded away their only elite player leaving them with no all-stars, and won a championship in the next 5 years?
I don't think anyone that supports trading Dame thinks they can win a championship in the next 3-4 years from either path. That is just something you made up so you could knock down.
