It's likely that Noah would throw more innings over his two years of control than Josh would over his four. Now of course, Hader's innings have been of a higher quality & come almost entirely in only the highest leverage spots, so the Mets would have to include one of Davis/Smith & more to even it out. If you want an established "ace" in return for Josh, I don't see us getting one that has equal or more control, just based on the volume difference between SP/RP. If Hader is dealt I would imagine that Stearns & company go for as much team control as possible in return. I still don't think Lux is going anywhere, but something like Ruiz/Gray from LAD plus a couple low level fliers the scouting/analytics department likes makes the most sense to me. If the Dodgers aren't willing to include Lux then no deal. Let them flop in the playoffs another few years.
