Tbh, as the parent, I will start preparing my child for the world of diversity, unlimited possibilities and open- mindedness. What happen is, your child have reached a fork in a road... What path she decides to take on that road can mean a lot in other life decisions... Good Luck in making that decision. ..
However, as a realist and math nut, the choice of riding/dying as a flyer or that road as learning to base/back reads like this, as a flyer on a team that maxes out at 20, there are usually 4 or 5 stunts groups, so in essence, flyers position needed on average is 5/20 or 25% and this same team will need at least 10 bases, which when I tabulate that 10/20=50% and backspots needed for this team of 20, I am guessing 5/20 or 25%... Looking at the totality of the situation, I think advising your child to diversify her skill set will provide her with more opportunities to play...js
