Who to Trade for for my 1-5 team

So I´m 1-5 in my full-point PPR league. Who should I buy low on? My team:

Brees
Ajayi
D. Martin
AJ Green
K. Allen
C. Fleener
D. Amendola
Streaming D
Streaming K

Surely there is a better TE to stream than Fleener?

Otherwise thats a solid team. Ajayi being poor has messed with you and Martin’s suspension.
An alternative to Amendola might be good even in full point PPR.

Buying low really would only be Thomas/ Julio if you went big. Maybe Baldwin or Bryant if you were looking for this week to find a player for Allen
