The thing I don't like about the Minor and Eduardo comparisons are the 3 point shooting. Everything I've read about Spangler (excluding this board), don't mention that as an option at all. And he didn't take a single shot from out there this season.
Ryan Minor made 9 of 21 threes his frosh year. 30 of 78 as a soph, 69 of 176 as a JR, and 62 of 191 as a senior.
Eduardo made 3 of 15 his frosh year, 13 of 49, 51 of 149, and 18 of 82 (don't remember him shooting so poorly his SR year).
I really don't see Spangler ever taking that many 3's. By all accounts he has less of an outside game than Osby, and he took what, 10 this year?
