Where people are drafted I think the factors go awards, ratings, stats, in that order. A while back I had a guy win NPOY but he was barely 800 rated and went #1. A few seasons back I had a guy who was the 2nd highest rated player in all of Tark with a 982 overall or something like that but he wasn't even honorable mention all-american and went undrafted. I had a guy that I fully think should be drafted based off ratings but I'm pretty sure he won't be since he wasn't even all-conference 3rd team. He has 93ath/83sp/96D/81lp/92per/88bh/71pa, if that's not an NBA player then there are very few guys that are.
As far as your guys I think Smith has the best chance, the only rating that isn't very good-great for his position his athleticism. I once had a very similar guy to him but I think he had 74ath who actually left early. But because your guy didn't win awards I'm not sure it will matter.
