If we look at the GSW as a model to emulate this is what they run...
Scoring PG
Shooting SG
All Purpose SF
Tweener SF
Center
Bench is built on versatility. They don't have a true PF that plays.
Using that formula we kind of have a poor mans developing version of it
Scoring PG - Lillard
Shooting SG - McCollum
All Purpose SF - Harkless
Tweener SF - Aminu
Center - Plumlee
I think this lineup suits Stott's system very well. The big difference between the Blazers and Warriors is the Warriors are better at every single position. the 2 SF positions in particular are lacking in the abiligty to shoot the ball. The other thing is the Warriors don't have a "Dominant" post presence on offense, Neither do the Clippers or Thunder. We need someone who can score in the paint but it can be like the way Draymond Green does. So evaluating the FA market I'm looking less for the "Traditional" position fits and more for the New Warriors age fits.
Also in terms of FA, Portland has a rare alignment of circumstances. Runner up COY, EOY. MIP, articles and reputation of Lillard being one of the best pure leaders in the league. The 2nd best backcourt in the league, 3rd youngest roster in the league, a team on the upswing, fantastic well known chemistry, a solid core and max $$$ to spend (like everyone else unfortunately)... But essentially aside from Market size, which is having less and less impact, the Trail Blazers have everything a FA would be looking for. Most teams are at the top stagnant, sliding down or at the bottom. Portland, Boston and Charlotte are the 3 teams already moving up. Agents see this as a massive positive. Portland is a buzz team and city.
