I think of Kevin Kiermaier when I think of Young. It's not quite perfect because Kiermaier when right has more power, a bit worse OBP, and never stole bases quite like Young, but the idea of a great defensive CF who runs and hit with a ~ .700 OPS is kind of what I hope Young becomes. The tough part is going to be the OPS, but if he can just maintain a .320+ OBP and run more than Kiermaier, he could have a long career even with an OPS closer to .650.
