In 60 games prior to the 27 he has played this year, Nava's career OPS is .711. He is hot right now, which is great, fun to watch. It won't last. And Crawford will contribute. He had a bad year. It will take him some time to get back into it, but if he is healthy again, he is too good not to contribute. Look at his career stats (career OPS of .773 plus speed). He is better than Nava.
