If football advice were given out like therapeutic advice blog posts (like this one on emotional intelligence):
It’s more healthy to gain yardage than to lose it
Running the football forward and passing it forward gains you yards. You want to do this. When the quarterback or running back gets sacked that is bad because you lose yardage. Sometimes players run in the opposite direction by mistake into their own end zone. That will cost you two points and the ball. Don’t do that.
You’ll want to score more points than the other team
You should try to get touch downs and field goals. When you get more points than the other team and the game time clock runs out, you win the game. The more games you win the better because then you can get in the playoffs and if you keep winning you could get in the Superbowl.
Being good at catching a football is important
When a quarterback throws a ball to his receivers, it’s important that they catch it. Being good at catching takes a lot of practice and you should really learn to do it well. If you are on the opposing team but not a receiver it’s nice to be good at catching as well as you can intercept the ball so your team gets to have it. Dropping the football is really bad, you shouldn’t do that. The other team could recover it.
A football is different
A football is not a basketball, it is oblong and has pointy ends. Throwing, catching, and running with it is different than other sports. Footballs have been inflated to their optimal level. It would be wise not to walk in on them being inflated or tamper with them yourself. You could even lose playing time for doing so.
