you have to let them set their blocks IE dont run so fast
any run can be good but you have to remember a couple key things
1. get a hat on a hat, if you have 4 blockers and 5 defenders you WILL have to make someone miss likely in the backfield or the point of attack aka audible
2. setting up blocks often means going slightly slower at certain points in the run(youll have to practice it yourself to see what i mean)
3. the kind of running back you have will determine what kind of runs are more effective IE Jovon Robinson i have is a power back who excels between tackles, but hes no burner and outside runs rely on always breaking a tackle as opposed to beating a safety to the outside
any run formation can be good, you just have to diagnose when you have a mismatch for or against you in number of blockers vs defenders
i abuse this to great effect
waiting on him to tell me when he ready
