One positive about Coale, and I'm taking a bit of a guess here, is that he seems to know his routes, where to line up, the playbook, etc.
I haven't read anything where he doesn't know his assignment.
That's a good sign, imo.
Of course, it will take him some time to get the rust off. But I would think as long as he is healthy, that another week or two of practice would do wonders for him.
