Input: Murphy was elevated to the eight-man leadership group for the 2007 season. In early 2007 Murphy replicated his good form of 2006, amassing 30 disposals against eventual premiers Geelong in Round 2. However, an injury to prime midfielder Nick Stevens after Round 3 saw Murphy attract the opposition's best taggers in most games. While _his_ form remained solid, shaking the experienced taggers proved too big a challenge for the second year player and he finished outside the top 10 in the club's best and fairest. <sep>, Pronoun: his <sep>, A: Nick Stevens <sep>, B: Murphy
Output:
B
