I know it's not really something they can fix, but that combined with the split step problem makes it incredibly difficult to play with a defensive baseliner online.
I just got SMOKED by ItaStallion 6-0 6-0....and he would have beaten me regardless, so don't think I'm blaming the loss on this. But there were a lot of points that I should have been in that I couldn't get in because I couldn't get my player to move back and forth across the court. I would be on one side of the court, try to get back to the middle, he would take one or two split steps then freeze and it'd be an easy winner. The character is designed to be a player who just sprints back and forth across the baseline (87 speed, 93 stamina), so when the game takes that away it just destroys the possibility of playing with that kind of player.
