This is a good question. Homers will scoff, and "realists" will agree with you. I will try and look at both sides.
On one hand, Dame and CJ are entering their prime, but so are Curry, Thompson, Green and Durant.
Dame and CJ are amazing, but Thompson and Curry are better....if for no other reason, defense.
Nurk is a stud, but can he stay healthy?
We have no one who natches up with Green and Durant AND they play defense.
We are young, but a lot of our youth sucks.
So do we see what we have in Collins and Swanigan, then ship Dame and CJ off for multiple picks and hope to get lucky enough to find players who someday will be as good as them now?
Do we continue to add role playing pieces in hopes to get lucky with an injury?
The league is 3 point happy, but do we continue to add 3 point shooters, or change the game?
To me, Nurk and if Collins turns out better than I hope he does, that is our advantage. We aren't going to beat GS at their own game.
Shutting down their shooters...or slowing them down, and pounding the ball down low is how to beat them. It's exactly what the Cavs did to them last year with Lebron.
It seems to me our bench needs to be more specialized. Harkless, Aminu, etc do things well, but nothing very well. Add guys next to Dame and CJ who compliment them...ie play defense first, but can also hit open 3s
So in conclusion, instead of rebuilding and hoping, adding the right perimeter pieces might get us competitive. Guys that will frustrate and piss off other opponents.
