I understand this is all complete speck. But if Purdue could sell him. Could Purdue and Stefan get away with playing 8 minutes a game at the 3 away from his natural 4 spot? That way saving more mins for each Haas and Biggie.
The thing is, I think the minutes that Haas and Swanigan will sit out would equal close to what he played at Hawaii this year (24.7 mpg). AJ averaged 24.6 mpg this season and Isaac only 14.3. Even assuming Isaac can take on AJ's workload from last season, which he may not be able to given the way Isaac gets called for fouls just for posting up, that leaves 15 mpg open at the center position plus whatever Swanigan leaves at the 4 (he averaged 25 mpg this year and I would figure that goes up to around 30 next season). I think that leaves a minimum of 25 mpg for someone as talented/experienced as Jankovic to come in and play.
As you said, all speculation. I just think it would make basketball sense from both sides.
