#3 Ricochet

Since signing for WWE in 2018, Ricochet has impressed wherever he has wrestled, be it on NXT or RAW. The former United States Champion was called up to the main roster earlier this year, under a year after being on NXT.
In NXT, Ricochet won the North American Championship, and had a memorable feud with Adam Cole on NXT.

We could perhaps see Ricochet back in NXT, and maybe even have a match with Cole or some other new Superstar for the first NXT show on USA Network.
#2 Drew McIntyre

Another Superstar who was in NXT previously and even held the NXT Championship is Drew McIntyre, who is currently out with an injury. According to Fightful, McIntyre may be ready to return to action after being passed fit by WWE.
We could perhaps see McIntyre return to WWE on NXT's USA Network premiere, where he talks about his NXT run and informs the fans that he will be back in action soon... maybe throw in a few Claymore Kicks to some poor NXT Superstar!
