There's no evidence to suggest the Jays are on average more aggressive with promotions than other teams. Their policy of two full seasons in rookie ball and short season ball for position players is pretty much identical to many other teams, it might even be slightly conservative. In the upper levels guys who are vastly outperforming their peers are being moved slightly faster than guys who are merely doing well, Pompey vs Nay for example, but this is everyone else does it.
I'm guessing a lot of people have problems with the Pompey promotion but its justifiable, he's got an advanced approach at the plate(12% career walk rate) and he's not really "breaking out" like people think he is, the only time he's ever struggled in his minor league career was in the first half of 2013 when he was just coming off of surgery. He was drafted a year ahead of Blake Swihart, you could argue he's been a better hitter than Swihart and they're both at the same level now, that's pretty much the norm for how quickly good hitting prospects move through the system.
