Kerryon/Allen Keeper Question

Who do I keep?
Keepers are kept for the round value they were drafted last year.
League Info.: Full PPR. 1 QB, 2 RBs, 3 WRs, 1 TE

My Current Keepers are (most likely):
Julio Jones (No-Cost)
George Kittle (10th Round)

Need to choose between:
Kerryon Johnson (4th Round)
Keenan Allen (4th Round)

Other Considerations:
Donte Pettis (14th Rounder)

Due to 3 WRs I’d go Julio, Keenan and Kittle.
