Snider is getting full playing time for the Pirates. Although he's hitting for a lower average his OBP is similar and slugging is a bit better. Both are unspectacular but dependable defenders. Melky supposedly has a plus arm but I don't recall a single OF assist this year. Both are slow as $h!t. I ask you - Is Melky worth 8M compared to having kept Snider at 500K? Discuss.
