Trey Lance Early?

1/2 PPR
I have Cousins and Tannehill as my QBs but want to optimistically pick up Trey Lance.

I have 6 WRS I’m holding onto and my lowest Id like to drop is Darnell Mooney
Is there any reason I should keep him over getting T Lance?

Thanks for any and all help

Yes, you already have two QBs, and Lance isn’t starting. That’s two GOOD reasons, and if you need a third, you’d have to drop a rosterable player to get him.

Is there any reason you would want to roster a third non-starting QB instead of a WR asset?
