League average for NL starting pitchers is 4.51. League average for starting AL pitchers is 4.64. Only two NL teams have team starter ERA's under 4. There are also only 44 qualified starting pitchers in the majors who have an ERA under 4 - 23 in the NL and 21 in the AL. So by your estimation, a majority of the starting pitchers in the majors aren't good. Sorry, I won't try to rationalize the pi** poor pitching of Marquis. You can say piss.
