Think it's likely that it should be the UConn coaching staff that lets Saniya know what her roles should be with differing units, starters and reserves rather than we BYers. Since she is basically the PG for the reserves, I'm guessing her assigned role is to be the floor commander who organizes the action and feeds Gabby and the rest for shots while occasionally sinking her own at that phenomenal rate of the last dozen games. But that doesn't mean she should become trigger happy, because even if she could sink a lot more, like Stewie she has a team function that comes before just shooting the ball.
Her role among the starters is different, and part of it is too just be dangerous enough so that she draws a defender to the outside and loosens up the paint. As previously noted, she does not get fed the ball much for good shots when she's in with the starters. That may change a bit, but I don't see her getting much more than the 4 shots she took against Tulane in the later Tournament action this year.
And the second Rebkell poster is just clueless and clearly hasn't watched any UConn games since November.
