I see it like this....
Kosi has some pretty impressive skills. I know that CIS is all down on him, but the guy was Mr. Football in Florida. That's a big deal. Jarren seemingly has similar attributes, although a little shorter. But what he lacks in height, he more than makes up for in accountability and general mental stability.
If I'm Diaz, and ONLY if we can land Hurts, I'd try to push Kosi out to ensure Jarren doesn't try to leave again. No matter what, you're bringing in one guy who may or may not start in 2019. If we don't land Hurts, we need both Kosi and Jarren on the roster. Ideally we can keep both of them. Otherwise, one of them will transfer, and I'll take the guy who has been quiet and isn't making instaporn.
