ERA tells the number of runs but not when they were given up. Not every run affects the outcome of the game the same. If we accept the idea that some people fold under pressure and others rise to the occasion, 2 people won’t the same ERA may be diifferent in how likely their team is to win.
A stat calculating win probability and the pitchers impact on it each time they give up a run could he’d light. I assume this exists somewhere...
