Yes, the 2017 NFL Draft is over 11 months away but that does not stop from early draft rankings from coming out now, and then being totally irrelevant prior to the first college football game.
This does not stop those form putting together position rankings and ESPN's most famous head of hair/draft guru, Mel Kiper, Jr., put together his top five players at each position.
Kiper was friendly to the Mountain West in these ranking positions, and he broke them up from seniors to underclassmen. So, this is not necessarily a definitive ranking for the draft but it does a nice job of including those who are draft eligible and seniors.
