I agree with that. The "unknown factor" is:
Could a better motivator -- and/or better disciplinarian, and/or better fundamental coaching
made a difference in that dudes development and production?
Maybe. Maybe not.
But the hallmark of a truly "great coach" (IMO) is his ability to get the most out of his players.
I don't think we do that.
At least I see no obvious evidence of that.
Your take?
In my experience, players motivate themselves. There are only a couple of archetypes of successful players in terms of effort/motivation:
1) giant - everything is easy because they are the best athlete. This ends at some level for almost everyone.
2) tribalism - needs to hate the opposition for internal motivation
3) external - they need an outside voice to hype them up. In my experience this is a very short lived bump
4) economic - motivated by glory, puss, money. “Contract year” players
5) professional - grinds his job, works hard, and does his best to win every play.
A team is a mix of all these types of guys. You need the tribal guys to hype up the external motivation guys. The giants, economic, and professional types don’t need it.
If you think about the fins, I am willing to bet Suh, RT, and Wake are professionals.
I don’t go to any games, so I have no idea who the tribal and external guys are.
Regardless, the influence a coach has is limited. Allow the tribal guys to be who they are and influence the externals. Stoke the fires of the economic guys.
Phillips is in the unsuccessful category, to this point. He fits none of those molds
