Josh Buchanan, who really knows his stuff when it comes to small school (AKA sub-FBS) prospects put out a list of his top 100 small school draft prospects this year. He's got 5 Bison on the list:
12. QB Easton Stick (projected 5th round)
22. RB Bruce Anderson (7th round-priority free agent)
76. C Tanner Volson (PFA)
78. CB Jalen Allison (FA)
96. Darrius Shepherd (FA)

Typically the number of FCS players drafted is in the mid to high teens although there was the lowest number of FCS invitees to the NFL Combine in years this year so it seems more likely that Bruce won't get drafted than he will but it sure looks like Easton is locked in as a draft pick right now.
