Thats a Generation ME problem if I ever heard one.
Less and less people can handle critizism.
A few years back I played for a 3.0 team and was the worst player on the team, I didn't get invited back the next season.
I wasn't happy about it, but in all seriousness, it makes sense to replace the weakest player.
I improved, and got recruited to a 3.5 team, in the City playoffs we played that exact team (by now mostly bumped to 3.5), I played in the winning 1st doubles getting us to sectionals, and sending them packing.
Either way, yes, just with everything in life if you are the worst of a certain group, you will likely get dropped.
