Keith vs WildTurtle

So we all obviously remember Keith from last split, coming into Team Liquid and even bringing along a decent fantasy score with him. Now there have been serious considerations of Keith replacing WildTurtle as the ADC for TSM. Apparently Keith is in the midst of scrimming with the team even.

Now just in terms of overall LCS stuff, I'm really curious to see how he subs in for a week. I don't honestly think WildTurtle is an awful player, but he has been slumping majorly this split in comparison to the rest of his team.

**However, this is a Fantasy LCS board. **In my one league, I have WildTurtle and Niels as my two ADCs, who have been steadily my ADC and flex picks respectively. In fear of someone else picking up Keith in my league, since he is available as a pick up, I'm not sure what to do. I don't want to drop WT and pick up Keith on a whim, because what if he doesn't end up subbing? Or what if it's only for one week? However, I also don't want to lose having TSM's ADC on my team overall, so I don't want to cling onto WT to only find out that Keith is going to stay on.

I kind of wish the person who has a player gets first dibs for like, a day or something on the sub that is incoming. Or some other stipulation. I dunno, I can also see the aspect of it just being fantasy and having to go with the flow.

Thoughts?
