Many analysts and commentators maintain that Miller is ok at around the 300-pound limit.
He may be one of AJ's toughest tests to date, but IMO Miller will need to adjust dramatically for this fight.
He will need to be in top condition, using upper body and head movement to make AJ miss, as well as getting inside and whacking away at that body - pressurizing AJ as he now seems to be boxing more off the back foot now than he used to.
Both chins could be tested as long as we don't get an anxious referee who jumps in all the time, nullifying any chance of an inside fight.
Miller has never been remotely tested in terms of opposition he's faced, while AJ has never fought a unit of this size who can really take punishment - being a former kickboxer - Miller knows the tough grind well.
As always with these fights, it could be either a 12 round bore, sparks in spots, or a barnstormer. Let's hope for the latter, and we'll certainly know more about where Miller belongs in this division afterward.
