Same problem Marina had for a while last year. Different role/expectations takes away from her aggressiveness. Difference is that she defers too much to begin with, unlike Marina's aggressive attitude towards shooting. I was frustrated that JY didn't take KLS off the dribble more especially once KLS had 3 fouls.
When Jackie plays point she doesn't do the other stuff we need like rebounds, putbacks, D, and excellent timely shooting. For Marina when she plays point she has to be more controlled. Still when game flow tells her she needs to do it herself (like taking layups they give the lane to her or the special 3 she can hit), she has the moxie to doit.
