I'm coming off of one season at Paramount, where my kid was on one of the higher-performing teams ... playing for one of the more "excitable" coaches at the club. This was my kid's second year of club volleyball, but we had heard a wide range of things about this coach and the club. We were somewhat prepared.
I don't know if this happens with every team at high-level club, but the coach definitely had some favorite players on that team. As a result, there were some entire weekends where a handful of players did not play at all. Flying from DC to Florida, Missouri, Atlanta, etc. and staying in hotels makes for quite the family expense only to have your kid not even get on the court during a single match. While my kid wasn't a starter, she did get on the court in nearly every set the team played last season.
I will add that having a player at Paramount gave us access to better/"closer-in" hotels during some tournament weekends than what we had experienced the year prior at another club. Having only to walk two blocks to the tournament venue vs. driving 20+ minutes and having to park at a convention center can make a world of difference. Forget something in the hotel room? No problem! I'll grab it and be back in 10 minutes! You won't do that if it requires driving and there isn't anything convenient nearby ... and open on a three-day holiday weekend. (SpotHero is still a go-to resource for me when I need it!)
As I hinted, this particular coach can have an outburst at any time, but **I** never heard any cursing or constant berating of a particular player during practices or matches. If anything, the bench players or a ref might get an earful during match ... and yes, there are some refs that won't play that game. With the coach having some favorite players, there would never be anything negative directed at any of them. When a set/match got way out-of-hand (thankfully, didn't happen repeatedly), seeing the coach effectively give up and just sit on the bench isn't the kind of energy or motivation the players need at that moment. If the team isn't performing as expected during a practice, I'm sure there will be a few extra sprints thrown in.
Heading into this upcoming season, I've heard from other Paramount parents (involved with other teams). They've shared some of the things that their player's coaches have said to players during matches last season and prior. There were definitely some things that crossed the line for me. So, I'm not going to pretend that kind of thing doesn't happen at this club. I'm just thankful that I didn't observe it for myself ... and I hope that my player didn't have to directly endure anything like that.
The only observation that I can offer on the Metro/Paramount dynamic is that it seems many of the parents know each other, perhaps from years on opposing (or the same) sidelines. Things might get loud when the clubs face each other on the court, but as soon as the match is over, I'll see parents chatting it up like old friends. I've also heard a Metro coach or two get mouthy with a ref. Certainly doesn't happen at every Metro match I've seen, so it may only be one or two coaches that occasionally act out a little.
Beyond that, I can only offer a useless spreadsheet to help folks navigate tryouts over the next few weeks.

Hopefully, it will help someone get a better "lay of the land" that is CHRVA.
