AJ is another example, when he was on Raw they tried to force this pitbull shit, the commentators were more aggressive towards him, but once on SD it felt like the grip of Vince was lighter, like Vince takes thinks easier on SD, since after all for him SD is and always going to be the B show.
Also we never hear that the scrip of SD had to be re-written at the last hour, and for Raw we get that form time to time, that just shows how much more involve Vince is on Raw than SD.
AJ stop being called the Pitbull the moment he impress Vince with the Roman matches and that why he was push on SmackDown
