I think Merrifield gets close to $15 on a multi year deal. He'll pass 3 WAR, and has been consistent. A lot of the guys you mentioned have some negative WAR years. Turner is a close comparable, age/history wise, he went into FA with a 2.4 WAR year. He ended up with what more realistically is a 1 year 16M contract. He has player option for 13.4M or can take a 6.7M buyout. Unless he suffers an injury between now and the end of season he probably opts out. I'm on the fence on offering Merrifield a QO.
