How much "technique" is involved here really? Were not talking passing or kicking or even running routes. Most of these kids on the team were the best player in their high schools, maybe in their conference in the case of the better ones. Maybe one of the best in their state. They've been playing the game since they hit middle school, if not sooner, before they got here. Tackling consists of grabbing the guy with the ball and not letting go. It shouldn't take years of college coaching to learn to do it. And if you didn't know how to do it before you got here, they shouldn't have brought you in.
