Diana had 109 assists as a freshman good for #9 for Uconn freshman in 33 games and 791 minutes.
Anna has 46 in 19 games and 449 minutes.
Anna does have nice vision and anticipation but DT was spectacular from her first game. They and every passer loses assists to missed shots, DT probably lost some to teammates not believing she could get the ball to them as well.
(DT did have the advantage of playing with a spectacular team around her as a freshman - probably the best ever at Uconn before the injuries crippled them.)
