How long do I hold on to drake?

I have Kenyan Drake, on one side, I love him as a player and think he has great upside if he gets the snaps. On the other side, he’s been a hit and miss and is getting disappointing, so I hold onto him longer or try and make a move now while he still has some value. I was thinking of targeting someone like Chris Thompson, Carlos Hyde or Jordan Howard.
Here’s the rest of my roster:

My roster is :


Dalvin Cook
Kenyan Drake
Mark Ingram
Kerryon Johnson
Corey Clement

Jordan Reed
Jared Cook

Keenan Allen
AJ Green
Sammy Watkins

You might be able to pull Howard for him with the way the bears a trending

I don’t think his value can go down, and he was used a lot more in the second half of the season last year. I think he’s a hold unless you can get legit value for him, which is pretty unlikely.
