Is there a faster way to earn xp as a linebacker in road to glory

I have just started a linebacker road to glory and I was wondering if there was a way other than adjusting the xp sliders. I find it very hard to earn xp especially if you haven’t really played as a defensive position in RTG. Also I feel like you should make it so you can choose which part of a position you want to play like TE or FS or SS or ROLB, LOLB. Just a thought.
