Lovie's defense not cutting it

I am getting sick of seeing our team worried more about trying to pull the ball out of the ball carriers hands than making the tackle. This crap doesn't get the defense off the field and that's what matters. If it works, it looks good but more times than not the opponent ends up happening and 2 yard gains turn into 8, 9, 10 yard gains. Maybe its just me. Id rather get three and outs than go grabbing for the ball and let the other team sustain drives that guts the defense...
