If they have time to be negative about their fellow program teams, then they aren't really focused on improving their own skills or team. Maybe they are on JV now, but if they are going to have sour attitudes then they aren't going to get far in life regardless.
Example: When I was in high school, I cheered with a couple girls that had elite tumbling since elementary school. They knew that they were going to make the team every year, so they didn't try AT ALL. They were downright mean in 9th grade, doing the whole "I'll invite everyone on the team except 2 or 3 girls to my sleepover", etc. and other childish things, which was tough freshmen year. I made other friends though and realized that I didn't want to associate with these girls anyways even when I did get invited. I had bigger goals in life than just talking behind other girls backs and trying to go to "high school parties". When we ran laps, these girls ran slower than a grandma walks. When we conditioned, they cheated. When we went to tumbling classes, they skipped and sat on their butts. Guess who ended up cheering in college + getting a 4 year degree at a top university and guess who didn't graduate community college?......In the end its about more than skills. Without a positive attitude, self motivation, and hard work put in, you don't get to your full potential regardless of where you start. As one of my favorite quotes goes "Hard work beats talent when talent fails to work hard".
Ignore their negativity.... its just a road you don't want to go down in my opinion, as these girls probably have other issues internally or at home that cause them to need to put others down. Telling the coach "they're saying mean things" will = tattling on them in their minds..... You could go to the coach however and say something along the lines of "I feel that there isn't much team unity between squads", which would be taken a little differently as you wouldn't be pointing out specific girls.
Overall though, I recommend you focus on being the best that you can be and not even giving these girls another thought. So what if you made the freshmen team as a FRESHMEN! That is normal! Many girls around the country don't even make any team at all. You aren't renounced to that team for the rest of your life! Enjoy the moments of cheering with new friends, being involved in your school, and getting to cheer on players that you'll actually know in your classes and such rather than worrying about what these girls think. Before you know it, you'll be a senior on Varsity cheering your last game and wondering where all the time went!;)
