"Let me explain to you. If a pitcher goes out and pitches 2 games of 6 innings at 2 runs and then pitches 1 games where he gives up 3 runs in 2 innings does that make a terrible pitcher? That would give him a 4.5 era so I guess in you mind he stinks. It is so sad that the educational system has failed you."
A 4.5 ERA is decent, I have not said it´s terrible. Now you are resorting to making things up. I´m gonna try to explain this one last time. Even poor pitchers have stretches where they rack up some starts with pretty good pitching lines. After all they are major leaguers. However one of the things that separates the poor pitchers from the good ones is that these stretches don´t come around as often or don´t last as long.
When looking at the effectiveness of a starter the most logical stat is the ERA. Every game is included in the ERA. All the best, all the worst, and everything in between (IP is also a telling stat but Hughes doesn´t do well there either) You could as you are create an example where the starter throws a quality start 2/3 times and somehow only pitches 2 innings albeit pretty bad ones in his 3rd. That´s not nearly the case with Hughes though. Over his career starting Hughes averages about 5.1 IP with a 5 ERA. He´s not giving the Yankees innings and he´s not pitching well. Even more concerning is that his results have been getting progressively worse.
