I think - in some ways - extenuating circumstances lead to differences in how they are perceived. AJ was able to grow on the job with a bad team, and as he got better, the team got better. Bazz won a national title as a reserve as a freshman and had nowhere to go but down.
Last year was rough on Bazz, and probably deservedly so as the point guard, but he basically had a similar year to AJ's sophomore year - flashes of individual brilliance but inconsistent, team was up and down, but got to the NCAA's. Even the personnel around them was sorta similar (Thabeet/Drummond, Adrien/Oriakhi, Sticks/Roscoe, Lamb/Dyson, Wiggins/Boatright off the bench). Only difference was it was a big leap forward and a building block in 2008, and a step back that led to nothing in 2012.
Now that Bazz has reached his junior year and has probably grown into his role well enough to lead the team somewhere, the team has nowhere to go. So maybe next year will be the one to finish his legacy as a Husky (although he basically ran the show the whole second half against Butler with Kemba off the ball, so I'll say that's a feather in his cap regardless).
