Pickup Devante Parker?

10 Team, 2QB, Half PPR,

Someone in my league dropped Devante Parker and I have Kenny Stills on my squad. Should I drop someone to pick him up?

I’d drop either:

Keelan Cole
Ryan Tannenhill

I have him stashed on my bench. I think he might do some later this year. I’m hoping anyway. I would drop Tannehill for him.
