bench sitter

Someone who's on a team, but sits on the bench and watches the best players On the team play the game.

He's not a good player he's just a bench sitter.

Bench Sitter Syndrome

When you are capable of playing, but the coach doesn’t put you in the game and you stay on the bench the whole year. Having this syndrome does not mean that you have a bad attitude, it just means the coach might bring up a JV player to play in a spot that you are perfectly capable of playing, and the coach never gives you a chance for zero reasons at all…..

I have bench sitter syndrome, the coach must not like me for some reason.
