Primary ball handler
Perimeter creator
On ball scorer
Off ball scorer
Perimeter defender
Defensive big wing
Offensive big
Defensive big
I would like to start creating a ranking (and tier) of top15 for each of these positions and see where the discussion would go from there.
My first one would be the perimeter creator, defined like this:
This is a guy who who will both score, organize the offense and create for others. He can also bring the ball up but he's the one often creating the advantage. Guys who relentlessly attack the basket are often in this group
Example: Luka, LeBron, Trae, Garland, Shai, Morant
This is probably the most valuable role today, that might define the ceiling of your team unless you can have a special combination of guys in different roles.
Assuming reasonable health and age related progression/regression over the next 12 months, this would be my list:
Tier 1
1 Luka
Tie 2
2 Lillard
3 SGA
4 Harden
Tier 3
5 LeBron
6 Morant
7 Haliburton
Tier 4
8 Garland
9 De'Arron Fox
10 Trae young
11 Siakam
12 LaMelo
Tier 5
13 Dinwiddie
14 McCollum
15 Brogdon
I consider most elite SG and SF "perimeter scorers".
Steph I see him more like an "off ball scorer" but this is actually tricky, he would be 1 or 2 in this list.
