"With the transformation of todays game, everyone handles the ball. What are you thinking? "
I have never seen Shawn Bradley bring the ball up!
I cannot see the differentiation between ball handling for different positions. Only a point does the most followed by the 2 then 3, 4 & 5 do little. The only ball handling i can think of is getting the ball up the court, fast break, penetration dribbling and in the post. All the same principles apply. When i played the three i usually dribbled in the post or one on one, i rarely bought the ball up only in a full court press. Playing the 2 requires me to do this sometimes, in fact far more.
"Swingmen are a teams most athletic player and best defensive player"
- not necessarily. I would say that from a defensive standpoint Centers would be like Ben Wallace, Shaq etc - most rebounds & blocks. Guards usually get the most steals. Carter isn't the most polished defender. I think athleticism is spread out through all positions you have your Steve Francis' Baron Davis' at the 1, Stackhouse & Kobe at the 2.
I would say swingmen are the most versatile player who have an all round game. As for me i can defend at either, just a little light when matched against 4's but usually jump over them.
