I think one thing to consider is that IU plays at a much higher pace than Purdue does. Per 100 possessions, Edey is at 42 and 26, while TJD is at 35 and 19. Defensively, before the season, I would have said TJD was much better, but Edey has proven to be one of the best rim protectors in years of college basketball by looking at how rarely Purdue opponents try to take the ball to the rim (#1 in country). I'd still take TJD there as he's a lot more versatile, but on an average night, Edey has actually been a good defender this season. But this isn't even a question right now when one guy is on a #1 team that had no preseason expectations and the other team has been a disappointment to this point in the season.
There are still 10 games to go that could change this, but IU being ranked preseason every year for having so much talent then floundering and using the lack of talent card really is something. How many 5 star underclassmen, POY candidates, and 5/6th year seniors do they need to admit to having some talent? Also can't forget the talk about all the talk of how Duncomb dominated Furst in one AAU and would be the better player but has 0 points in Big Ten play in 2 years.
