I never played high quality competition so take this with a grain of salt.
To me it does. When in play, I'm the guy who sets picks and pops out at atound the three point area. I like to do a pump fake, one dribblethen launch move and to me it gets me to a better rhythm. I tend to set my feet better after the dribble too. And I think it works with others as well.
I would saybyes, but thats just me. I am better shooting after the dribble though (most of them are 18-20 foot jumpers).
