Detroit anyone? Boston anyone? San Antonio anyone? The averages are a bit higher than 10-15, around 17-20, but you get the point.
In the Denver game it was even more exaggerated. 73% of the offense came from them. My point is that 60% shooting isn't sustainable by anyone, and if you've only got 3 guys doing it to begin with, well...........
No that's not balanced at all. Good that they are doing it, but they need someone else to help out with the load.
Do I really need to list the teams that fall into your category but are not making the playoffs? You make it sound like your team should have a squad where everybody harmoniously scores around the same amount of points. There are more examples of teams that suck that do that then there are of teams that fit that bill but have a ring. Yes, you want contribution from guys. However, you can do it in more then one way.
Let's look at a couple of the teams you mentioned. They have guys in their starting lineup averaging less then 15 PPG.
Spurs
Bruce Bowen = 6PPG
Finley, Udoka, Thomas or whomever = less then 10 PPG
Boston
Kendrick Perkins = 7.4 PPG.
Rajon Rondo = 10.7 PPG
See what I am getting at? Most teams don't have balanced scoring like your suggesting. More teams do not. However, there is more to a balanced roster then scoring. Rebounding anyone? Defense anyone? Assists anyone? Steals anyone?
Sorry but I don't get the point. The Suns are about as balanced as they come.
