wally judge = "Wally"
rodney mcgruder= "Rod"
nick russell = "Russ"
jordan henriques = "Jordan"
curtis kelly = ck (confirmed) - can't argue with confirmed
These are quite likely.
However, I WISH they were the following:
wally judge = "Wally"
rodney mcgruder= "McGruBer," funnier that way
nick russell = "Ucklaw," in reference to his mythical offer from UCLA
jordan henriques = "Jo Jo Hen Hen," he needs to be twice the size, so start saying his name twice and maybe the prophecy will self-fulfill
curtis kelly = the Owl
Martavious Irving = "PURE" (previously undetected recruiting error)
