A bit off topic, but relevant: here's an excerpt from an article about cap allocation (link to full article below):
FORWARDS
Main Role Players: 1C, 2C, 3C, 1W, 2W
Supporting Role Players: 1W, 2W, 3W, 3W, 4C, 4W, 4W
Max % of Salary Cap:
- ~14% to 1C (about 10.22M of 73M)
- ~10% to 2C (about 7.3 of 73M)
- ~7% to 3C (about 5.1M of 73M
This was from 2016 when the cap was $73M, but the interesting thing is that this person groups the top 3 Centers plus (only) 2 wingers as the most important forwards. I can't say that I disagree with that.
