Input: Consider Input: Passage: Prior to his junior season, McKinney was projected as a first round selection in the 2015 NFL draft. On January 9, 2015, McKinney announced that he had decided to forgo his senior season and enter the 2015 NFL draft. Before the start of the pre-draft events, McKinney was ranked as the second best linebacker in the draft by NFL analyst Mike Mayock. He was one of 34 collegiate linebackers to attend the NFL Scouting Combine in Indianapolis, Indiana. McKinney completed all of the essential combine drills and finished second among all linebackers in the vertical jump, fifth in the broad jump, ninth in the short shuttle, tenth in the 40-yard dash, and tied for 11th amongst his position group in the three-cone drill. On March 4, 2015, he attended Mississippi State's pro day, but opted to stand on his combine numbers and only performed positional drills for the team representatives and scouts from 29 NFL teams, including New York Jets' defensive coordinator Kacy Rodgers and New Orleans Saints' assistant head coach Joe Vitt. As a highly sought after prospect, McKinney attended private visits and workouts with multiple NFL teams, including the Philadelphia Eagles, Dallas Cowboys, San Francisco 49ers, Baltimore Ravens, Miami Dolphins, Carolina Panthers, Cleveland Browns, Denver Broncos, New Orleans Saints, Chicago Bears, and Minnesota Vikings. At the conclusion of the pre-draft process, McKinney was projected to be a second round pick by NFL draft experts and scouts. He was ranked the third best linebacker in the draft by NFL analyst Lance Zierlein, was ranked the fourth best linebacker by Sports Illustrated, was ranked the fifth best inside linebacker by Charles Davis, and was ranked the fifth best linebacker in the draft by NFL analyst Mike Mayock.
