Big difference between doing it in October and doing it for the next five months. I love Ranger - easily my favorite player ever since his '22 performance in that very same surprise bullpen role - but he like he said, he wants to start, and if the Phillies actually did seriously propose otherwise, he would keep his mouth shut but his agent wouldn't.
It all remains in the "nice problem to have" category if they get to October (and with six healthy SPs, not even counting Painter).
