Me and my nephew have done this... if you plan to play the "my career mode" .. you can be an instant star at the team you have drafted... simply accumulate 500 sp points... you can do that by simply play rookie showdown and be drafted by a nba team... when you have 500 sp points, go to the jumpshot package and pick ray allen's jumpshot package... if you notice after you purchased the ray allen jumpshot package, sp points get negative. go to the attribute sections and make every attribute on the maximum level.. then you can purchase the section's like posterize, highlight film... and make all of it in its maximum possible(depends upon your my player's attribute rates). and so with the animation section (dunk package, jumpshot etc.)... you can do this once...
