This is pretty close to bang on what I was going to say. His Defense is unreal, and he has the range to get everything, but using a Crawford is just as close. Only thing Ozzie bring to the table besides defense is so good speed. If your line up is deep enough, then he can be worth it to shut down the middle, but in my opinion, besides a few slap hits the other way. he doesn't help enough.
If he had either some contact or some power he could be valuable, but bsides a high vision, he really doesn't have any other skills besides bunting and speed, and he's not a burner. I would say worth the grind cause he is fun to play with from time to time, but not worth it to go get to be the every day SS.
If you want to try out how he hits, use the FB Crawford card, they are pretty much the same thing.
