What should I do to improve my team?

10 team .5 PPR and I am pretty short on receivers. I lost this week, partly because I bought into the "Marshall wont play" bullshite.


Starters:

QB: Stafford
RB: Forte
RB: L. Bell
RB/WR Flex: Chris Johnson
WR: Marshall
WR: Vincent Jackson
TE/WR FLEX: Kendall Wright
TE: Julius Thomas
D/ST: Tampa Bay (been going week to week)
K: Phil Dawson

Bench:
RB: Mark Ingram (out for a month)
RB: Terrance West
RB: Jonathan Dwyer
WR: Rueben Randle
WR: Riley Cooper
WR: Allen Hurns
TE: Ladarius Green
TE: Levine Toilolo


We have an IR spot so I'm hoping Ingram will be IR eligible.

Do I need to look for more WRs? Vincent Jackson has been under performing so far. And I don't know how I feel about Kendall Wright at that Flex. Should I attempt some trades or search the waiver wire?
