I think consistency is where there's the most room for improvement.
If anyone playing in a Quartet could only get through the piece twice and they couldn't replace him they would have to pick something easier like a Mozart Hunt Quartet or an early Haydn one. Kinda like how McCoy had to call QB draws on 3rd and 16 all the time.
It is not like a Quartet could allow a bad Violinist to scratch his way through the Allegro, Meno Mosso e Maoderato, Allegro, Fuga etc... movements only to have him rock the last few bars of the Meno Mosso e Maoderato at the end.
