OK, that part was pretty damn good but I saw a lot of plays where he has obviously been watching our defense tackle.
Most forms of football have a move known as a tackle. The primary purposes of tackling is to disposses an opponent of the ball, to stop the player from gaining ground towards goal or to stop them from carrying out what they intend.
Our defense has not done this in four years.
They teach it right even in youth:

The first thing to remember if you want to prevent the other team from scoring, is tackling. Tackling is, bar none, the most important skill in football, and the one that can be taught the most easily if the coaches push hard enough.
Insist upon proper tackling. Don't ask, demand.
I use a four point tackling technique. Deviation from, or improper demonstration of any of the four points will get the offending player sent to remedial tackling, where they work with a coach until they have tackled a dummy correctly five times. This coach should be well trained in your tackling procedure and standards, and should consider this his primary job for the season. Poor tackling in scrimmages and drills can also cause the player to lose their position on the depth chart.
Always block and tackle with your head UP!
My four points are as follows:
1) HIT!
The tackler is to drive his shoulder into the ball carrier's thigh pad, and nowhere else! His head should be across the runner's body and up. His hips should be under him. There should be no bend or arch to the tackler's back.
2) WRAP!
The tackler should fling his arms around the ball carrier's legs and pull the runner towards him with a sharp motion. His fingers should be grabbing cloth wherever possible.
3) LIFT!
The tackler should lift the ball carrier slightly (roughly an inch or so). This serves three purposes: it keeps the tackler on his feet, preventing dives and misses; it breaks the runner's balance and contact with the ground, and it makes the next point easier.
4) DRIVE!
With short choppy steps the tackler should power the ball carrier across, rather than back along, his initial motion.
