Basic Help

Aight, i use the Raiders and my defense pretty much locks down EVERYTHING, except i give up occassional huge plays to the HB in the flats cuz i user cover the RB man to man with the FS, but i struggle reading defenses. i can only tell if its man or zone, is there any way i can get more info by looking at the defensive setup? just need some help with reading plays.

its easy to now what they in..the conerback will be looking at ur reciever for man...if anyone drops back deep middle of field...just see how many of em do...if 1 does then its cover 1,2 then its cover 2, etc etc and if a safety comes towards the box hes blitzing...
