Yeah it can get brutal when you play against a stud RB. Especially a shifty one with speed. You really have to commit to stopping the run when you play against a stud RB.. I'm loving the challenge though. It forces you to never make a lazy play call because you might pay for it.. I've never played with all of that assist stuff on but I don't see it having any negative affect on my sliders if you decide to use it..
