I mean...I can kind of see the idea of "garbage man" if you're talking about the offensive style that Dwight Howard has played for most of his career (lots of offensive boards, lots of dunks, etc.). Maybe AD's skillset will be shrunk down to something more limited as he gets more comfortable and accustomed to playing at a higher level.
But I think his offensive tools are a lot better than Howard's and in terms of production I think he'll definitely be top 2 or 3 on the team in pts, rebs and assists.
I think the main questions are:
1. How good/efficient is he going to be in the post when it comes to finishing hook shots or shooting free throws?
2. How will he handle the pressure of high expectations?
3. Will he face any kind of foul trouble or issues on defense?
If he does well in those categories he's going to be an absolute monster.
We're talking 15, 10, 2 and 2 or something like a per 36 of 18, 12, 3 and 2.
