I know you put the qualifier in there, but why the hell would the Sox trade Lopez, Walker, + when Luis Robert is going to be up the second week of the season who probably has a floor of around 2 WAR? That just doesn't make sense.
Not really sold on Nimmo either. If they are going to give up prospects for an OF it has to be a young, slugging, LHH. If that isn't available then you just give up money in FA for a slugging RF.
