All eyes have shifted to a stage in Chicago for tonight's first round of the 2016 NFL Draft. Here are 10 numbers of note about the Vikings, draft history and this year's pool of prospects:

4 — number of times since 1967 that the top two picks in a draft year have been traded; Tennessee sent the top overall pick to Los Angeles, and Cleveland dealt the second spot to Philadelphia in recent separate trades; the third pick also was swapped in the three previous times (1967, 1975 and 1997); San Diego has that spot

6 — most picks ever taken from one school in one first round (Miami, six in 2004); Ohio State will have five players in Chicago who could hear their names called Thursday; Southern Cal (1968), Miami (2002) and Ohio State (2006) are the only three schools to have five players selected  in one first round

7 — years in a row in which at least one Alabama player has been drafted in the first round; the active streak is tied with past streaks by Florida, Ohio State and Pittsburgh for the third longest ever, behind Miami (14 years, 1995-2008) and Florida (nine years, 1983-91)

8 — selections the Vikings are scheduled to make; Minnesota made 10 selections last year and nine of those players are on the roster

10 — minutes allotted per team to make a selection or trade once it is "on the clock" in the first round; the amount of time drops to seven minutes for the second round, five minutes for rounds three through six and four minutes in the seventh round

14 — number of players selected No. 1 overall since 1936 who have been enshrined in the Pro Football Hall of Fame, including Ron Yary, who was drafted by Minnesota in 1968

18 hours, 5 minutes — amount of time that teams were on the clock during the 2007 draft, the longest amount of time for a seven-round draft since 1967; the year that also included the longest first round (6 hours, 8 minutes); the shortest draft in that span was in 2015 and lasted 13 hours, 45 minutes

25 — college prospects are scheduled to attend this year's NFL Draft:

CB Eli Apple, Ohio State, RB Ezekiel Elliott, Ohio State, DT Robert Nkemdiche, Mississippi, DE Joey Bosa, Ohio State, QB Jared Goff, California, LB Reggie Ragland, Alabama, DT Vernon Butler, La.
