Help Identifying Weak Spots for Playoffs

As the title says, I’m looking to add depth for playoffs.

QB: Allen
RB: Jones, Dillon, Henderson, Michel, Swift
WR: Hill, Kirk, Beasley, Corey Davis, Claypool
TE: Arnold, Thomas, Knox

Thomas is in my IR spot rn but I am planning to drop a TE soon more than likely.

I’ve been streaming defenses and kickers each week. Is that still okay, or should I lock one in? I am consistently 9 or 10 in waiver order due to my record.
