This is the first of many, many, many 2015 NFL mock drafts that have the Kansas City Chiefs selecting a wide receiver. When your team hasn't caught a wide receiver touchdown entering Week 16, it's zero surprise to anyone that mock drafters will be sending receivers their way.
ESPN's Todd McShay's first mock draft can be seen here. He has the Chiefs selecting West Virginia wide receiver Kevin White, who is listed at 6'2 and 211 pounds. He is considered to be one of the top receivers in the 2015 draft class (which is hopefully as good as the 2014 class).
White is rated as the 15th best player in the draft, according to Mocking The Draft's top 100 players rating. Back in November, Mocking The Draft actually had White higher than Alabama WR Amari Cooper (not so much anymore). Also in November, they had White going 15th in their mock draft.
McShay has the Chiefs drafting 17th in his mock draft. If the Chiefs make the playoffs, that would definitely change and they would be drafting in the 20s. If they don't make the playoffs, 17th is feasible for them.
