#1 Should not be fired- Randy Orton
Randy Orton is one of the few Superstars who has not changed his brand during the Superstar Shake-ups and has been a key performer on the blue brand. Orton getting fired makes no sense since he is already involved in a feud with SmackDown's Tye Dillinger (who is currently nursing an injury). The Viper is also one of the most consistent superstars at Survivor Series and team SmackDown cannot afford to lose their most vicious superstar.
Also, Randy Orton being a veteran heel needs to stay on the blue brand as there are only a few talented heels on the SmackDown roster. He can have exciting rivalries with Tye Dillinger, Daniel Bryan or could even be the next challenger for AJ Styles' WWE Championship. Given that Randy and AJ have never had their dream feud, Orton's move to RAW may disappoint the WWE Universe.
