By all means let's trade away our entire team for a brilliant but injury prone center who is good for 55-65 games a year, with an immense cap hit now entering his 30s
First, it's better if you make your point without colossal distortions. No one talked about trading away "our entire team."
Second, you sound more like a fabulist than a realist. You've seen the combo of Thibs, RJ and Randle for a few years now, but you're dreaming that this is the year they don't get manhandled in the playoffs (if they reach the playoffs)?
Wake up! They are who they are! And one talented and plucky point guard can't radically change that.
If you want a team that can fight for a place in the playoffs for the next 7 years, sometimes even getting to the second round, then cool! We're moving in that direction. Anything more is a pipe dream.
Meanwhile, we DO have draft picks and talented players and contracts to wield for someone transformative. So yes, I don't believe reaching for an immensely talented and impactful player is absurd, and I don't think the front office does either.
