Green is a plus defensive CF, which means even at a 700 OPS you are probably happy to start him. He's putting that up now at age 22 and still has plenty of upside to improve over his next 3 yrs and 1000+ PA. Could he burn out? Sure, any player can at any time.
It's true Tork's situation is different. At 1b he has to produce more with the bat. BTW he shares the team lead in RBI.
I don't know if it's fans everywhere or just in Det, but sometimes there is a real tendency to let the perfect be the enemy of the good. Riley isn't Mickey Mantle, he's a bust!, Jerod Goff isn't Mahomes, bench him! You can win a lot of championships with a good depth of good players and zero superstars.
