Because he went to Belmont. I'll bet PKM and only a handful of others actually know where Belmont is and what conference they play in (I'll admit I had to look it up). Wesley Matthews went undrafted too. There are always a handful of guys that are overlooked due to their size or where they played. Second round is often the place to go after young foreigners so you can retain their rights while they develop. Sometimes you have a small bidding war for U.S. players who didn't get picked. In this case, he was on the radar a little bit (since he played in both SL's), but really vaulted up the charts with his shooting. I like that DL signed him for 2 years. If he works out, Jazz have his rights. If not, it's a team option.
Nashville. I have a couple of friends who go there, had no idea they had a basketball team that anyone cared about/could produce NBA talent.
