Haveing trouble trying to play the 4-3 defense

I am having the hardest time trying to relearn how to play this defense scheme the 4-3 defense. I have trouble bring the blitz also trouble trying to stop the run and less not talk about trying to stop the pass. So i ask is there a thread or someone in the forums that knows the in's and outs on how to play this defense the correct way. If you do know could you explain to me the way in which it should be done. THANKS im out ALC

Learn how to setup your base coverages. Learn the strengths/ weaknesses of the team that you are playing with. Figure out what fits your personality. For ex. prefer playing cover 2 or cover 3. Like to blitz, bend dont break type of defense.

Personally, I try to play base cover 3 until they get on my side of the 50 then I will start bringing pressure.
