 Now that we've taken a look at how you rush and how you pass and how the offense gains yardage Let's take a look now at what the defense is trying to do because the defense is trying to stop The offense obviously from gaining Yards and scoring those points because they want their team's offense to get out there on the field and to be able to To score points of their own so how is the defense going to try to stop them? One of the the biggest ways that they can do that is to force the ball Or to force the offense to turn the ball over and to cause something that is called a turnover so to turn the ball over means that At some point during the play The offense will lose the ball to the defense and there's two ways That this can happen two ways that the offense can turn the ball over first way is called an interception and then the second way Is called a fumble The fumble of the ball so these are the two ways Interceptions and fumbles are the two ways that the offensive team can turn over the ball to the defensive team Let's look at the fumble first because really the simplest way that they can do it It will generally occur and I mean it could technically it can occur no matter who has the ball But a lot of times you'll see it will happen either to the quarterback or to the to the running back And basically what this means to fumble the ball just means that they drop the ball And then so the ball gets loose Guys will try to for both teams then we try to jump on top of it and control it for their side and for their team But if in the event So running back drops the ball they fumble the ball and a defensive player jumps on top of that ball they would have Recovered that fumble and so the offensive teams and then turn the ball over to the defensive team The defensive team would then get that ball Right there on that spot and then their offense could come out and try to to score So that's a fumble to simply dropping the ball If in the event the offense of team is able to jump back on the ball And then they would just get the ball there and they would continue from that point There's the second way that you can turn a ball over is called an interception And this is if in during a play So let's say we're gonna have a passing play. So our Wide receivers they'll run out for the routes whatever the routes are maybe this guy runs out and then goes across A lot of times you'll see the court the corner back not the quarter the corner back on defense. He will be covering a Wide receiver So basically This corner back no matter where this wide receiver goes He is told to follow them. That's got a man-to-man coverage and there's different ways that the defense will Have different coverages that they will have But we'll take a look at that down the road sometime. So Let's say for this by we have man-to-man coverage This this corner back is covering this wide receiver this corner back over here is covering this wide receiver So no matter where they run these The job of the corner back is to to basically stop the pass from being completed If a quarterback throws the ball to his wide receiver, he catches it. That is called a completed pass So the corner back the defense's job is to to try to prevent those completed passes So let's say we have these routes Our wide receiver runs out and then across and then the the corner back He'll follow him maybe and he'll probably try to get in between He's remember this quarter quarterback will be dropping back to throw the ball So the the corner back will probably try to get in between the quarterback and the wide receiver and if he can do that Whenever the quarterback throws the ball that corner back will then have a chance to catch the ball Instead of the wide receiver. So we'll kind of try to jump in front of him He's not allowed to really push him out of the way That would be a penalty, which we'll look at all the things the ways you can legally Defend the guy here soon, but but the probably the simplest way it would be just to jump in front of the ball And to catch it For the defender and then of course maybe the ball slips out of the quarterback's hands As long as that ball doesn't hit the ground Then the defense has the chance to intercept the ball The other thing it wouldn't so that would be an interception That would be then a turn over that corner back if he catches that ball. He can try to run Run and pick up yards of his own or if he's then wherever he is tackled That's where his team would take over on offense The other thing he can do that wouldn't be an interception But would help the defense is if he just knocks the ball down or if anything other than the the wide receiver Catching the ball basically so if the ball is dropped Or if that cornerback is able to knock the ball down so that it touches the ground as soon as the ball touches the ground Then that pass is what we call an incomplete pass So it's an incomplete pass that means that the The pass would have hit the ground or run out of bounds or something like that. So so basically they The offense gains no yardage and then instead of being maybe first in 10, then it would be second in 10 So they don't gain any yards that will lose any words and they just lose kind of that that down. So And then the other thing of course that could happen is if a Wide receiver Does catch a pass The pass is completed. He does catch it and maybe he turns and he's trying to to to run up the field to gain more yardage As he is running if the ball was knocked out or he drops it for whatever reason Then it would be a fumble And so then the defense Would have a chance to try to jump on that and recover the fumble for their team as we said So they could be an offense. So that's what that's how turnovers work Interceptions when the defense catches a pass Throw him by the quarterback or a fumble when the offense drops the ball and Then the defense would recover take the ball over for themselves
