Presumably Nola did not get a NTC because both sides figured it would be moot. Trading him would be the easiest swap for Ranger (probably year-for-year and dollar-for-dollar at this point) but probably not gonna happen coming off of this particular season for Nola even if they wanted to do it.
If the Phillies want to go all-out to keep Ranger, trading Luzardo is the easy move. They could also keep him until Painter seems settled. I just still feel like they already decided last year that Boras's ask was going to be too big, and the durability question still too real. The former certainly hasn't changed, maybe the latter has.
But it still really comes down to whether Middleton wants to play in the same economic ballpark as the Mets and Dodgers. Even if you trade Luzardo Ranger would add about $13-15 million more than Luzardo to next year's payroll when, on paper, they really only have enough to replace (or re-sign) the other FAs (JT, Schwarbs, Kepler, Romano, Ross). Replacing Kepler with Crawford and/or Bohm with Miller (regardless of exact position) saves you another $20 million I guess, but will they do the latter? And if they do the former would we still rather have this kind of rotation but the same feeble OF (Marsh/Crawford/Casty because no money to spend on anyone else).
