Increase or decrease of team?

12 team league .5 PPR

Give: Tyrek Hill and Tevin Coleman

Receive: Kareem Hunt and Michael Crabtree

Current WR: Hill, Corey Davis, Nelson Agholor, Josh Gordon, Kenny Golladay and Antonio Callaway

RB: Bell, Coleman, Lewis, Jay Ajayi

I’m weak at RB and this would help. But it would also make me weak at WR. Thoughts?
