When you switch positions I think the most important thing to remember is there is going to be a learning curve. You’re a beginner at your new position and that’s how you have to approach it. Don’t come in with an arrogant attitude and pissed off you had to switch, come into the situation humble and ready to learn. Ask 100 questions about the position to make sure you have an idea of what you’re doing, after practice go watch 1-2 hours of film on yourself and on how the other Lbs on the team play a certain situation. Go watch videos on how professionals play the position. Learning visually before actually going out to practice is one of the best ways to improve your skills. Let’s say you’re switching from QB to WR, that’s an easier transition because you know everything the WR needs to do because QBs are Offensive Coordinators on the field, or at least they should be. But let’s say you’re switching from like DB to WR. If you don’t go into every meeting with a notebook and a pen to take notes, you don’t actually want to get better and you’re doing it wrong. You need to be willing to humble yourself and learn when you switch positions. That’s how the transition becomes smooth and you actually start to play well.
