You are contradicting yourself. This is what happens at times when people construct lengthy posts.
You are saying UofL needed one guy to get buckets on his own, then you are also saying they needed Gorgui, Chane, Look, Peyton, and Russ to develop...that's not so "simple" either, as you put it. Nor is it just "one guy" getting buckets on his own.
Also, you listed 5 guys - that's a team. Not one guy.
Furthermore - clearly UofL needed Henderson to get by Wich St. Blackshear, Harrell, and Ware were also steady contributors to the team.
So really UofL needed lots of guys, not just one guy to get buckets on his own.
Also, UofL always has at least one guy that can do what you say - get their own shot. From Russ, to Terry, to Mitchell, and prior to those guys Reece, Cisco, Williams, Clark, Sosa, etc, etc, etc.
For UofL to go the distance they need a strong experienced team that can excel on both ends of the court.
The D has remained top shelf, but the O has dropped off.
