You could just do what I did pensfan, drop run block and fumbles back to default at 50. Works good for me. I can't stop the run worth a damn either
Part of it is because I'm so use to abusing the hit stick lol. And I've been made to look silly a few times.
Also find a way to simultaneously up your stick skills and your understanding of pursuit angles. Especially if your usering a LB or S. That will help.
