Opposition quality refers to opponents level of play last year: 10 - faced all MLBers, 8 - avg of AAA, 7 - avg of AA, 5 - High A, 4 - Low A and 1.5 to 3 short-season players.
Players who did not appear in a major or minor league last year do not affect opposition quality (Lackey in 2012 or Darvish in 2011).
