Not sure their criteria but I agree it's a strange list. If James Milliken is Creighton's breakthrough player, the Jays are going to have a rough season. I could have named about 4-5 guys who fit better here- Huff, Thomas, Krampejl, Watson.
He does open the article by saying that no newcomers were going to be addressed in the list - for he Jays I'm guessing he flipped a coin between Groselle and Milliken.
