Baldi Fraschilla has discussed him a lot, believing he has the most pro potential of any college aged Euro in the 2016 class, per NBA folks, and that he should be viewed as a top 25-50 HS US player. Fran covers the Euro stuff extensively, so I take that evaluation as a big time positive.
Remember that Fran liked Mussini a lot too, but much much less than Freudenberg. I read stuff where he said that Mussini was more of an immediate impact guy at the mid major level, with the potential to be a good high major player with increased strength and quickness.
