What to do in first place

I have never started a fantasy season so well ever. I am 7-0 rn in a 10 man PPR league. Should I be doing something to prepare for playoffs?

My team is as follows:

QB: Drew Brees, Jameis Winston
RB: Melvin Gordon, Kerryon, Jordan Howard, Fournette, Smallwood, Jalen RIchard
WR: Deandre Hopkins, Tyreek Hill, Robert Woods, Allen Robinson, Taylor Gabriel
TE: Jordan Reed
Defense: Bears
Kicker: Dan Bailey

I’m thinking my most glaring need is to upgrade kerryon to a concrete RB1 but Ive been trying hard and can’t seem to do it. Thoughts?
