There usually is still quite a bit of movement b/w teams in 8th grade and slightly less in 9th grade as the better teams are usually looking to fill specific needs vice wholesale changes by then. Even in HS some teams will cut players or have players move teams (reclass) for more playing time. As for the post asking about cuts and Covid, I've seen large turnover (up to half the team some years) every single year on my kid's team all the way from 5th grade to HS. It's rare to find a club that will simply develop what they have all the way through the years. Don't let anyone fool you, ALL the clubs will part ways with players to get what the "perceive" as a better one. My kid has teammates from previous years that are on their 2nd/3rd team since the 5th/6th grade years. Bottomline is if they aren't playing much, you're better off finding a team where they can contribute and grow vice wait for the cut to happen in 8th/9th grade.
