My name is Matt Kelley. I am a Jerick McKinnon Truther.

What is a Truther? Most fantasy analysts harbor an irrational conviction for one player who has yet to break out despite three or more years in the NFL. Last year, a handful of Adam Thielen Truthers were rewarded with a heartwarming, 26-year old breakout story. Unfortunately, most Truthers eventually concede defeat, slowly remove their favorite irrelevant player’s jersey, and slink away into the hot take void. The wounded fantasy analyst then turns his or her attention to another fringe NFL player. The new/old player inevitably slides into the bottom rung of the delusional fantasy analyst’s preseason sleepers lists, inspiring hollow rhetoric to rationalize away player shortcomings and exaggerate ability. Rinse. Repeat.

My name is Matt Kelley. I am a Jerick McKinnon Truther. Hear me out on this.

Athleticism to Burn

McKinnon is still relatively new to the running back position. McKinnon played quarterback in a read-option system at Georgia Southern before converting to running back during the predraft process. Then, McKinnon did the impossible at the NFL Scouting Combine. He hit the 92nd percentile or above in every workout metric from 40-time to agility to bench press.

According to Harvard, the NFL Scouting Combine actually matters, and furthermore, athleticism matters most for running back prospects. Specifically, McKinnon’s astounding 32 bench reps -with him weighing 209 pounds – is the highest ever recorded by a running back, and his 155.7 SPARQ-x Score, NIKE’s comprehensive athleticism metric, is the highest of any RB on PlayerProfiler.com. McKinnon is the most athletic running back in the NFL based on measured speed, burst, agility and power.

Positive Comparables

Based on size and athleticism alone, McKinnon’s list of comparables on PlayerProfiler illuminates his playmaking ability:

All six comps have experienced degrees of success in the NFL. However, not all explosive running backs fire in the pros. If we expand the parameters to include non-producers, McKinnon’s athletic profile is also similar to the following irrelevant running backs:

Donald Brown

Bishop Sankey

Michael Ford

The positive comparables far out-weigh the unfortunate comps. Moreover, just by sticking on an NFL roster for four consecutive years, McKinnon broke free of any Bishop Sankey and Michael Ford comparisons.

Snakebitten in Minnesota

McKinnon has experienced a snakebitten tenure in Minnesota. After the Vikings selected him in the third round of the 2014 draft, he was immediately thrust into a major role in the wake of Adrian Peterson’s season-long suspension. Though he was new to the running back position, McKinnon posted 538 yards on 4.8 yards per carry in his first NFL season. An impressive feat.

Peterson returned to glory in 2015 only to miss most of 2016 with injury. The Vikings bequeathed the starting role to McKinnon in 2016, but his efficiency collapsed. After finishing near the top of the league in yards per carry and yard per touch during his first two seasons, his 3.9 yards per touch checked in near league-bottom as he managed just two breakaway runs all season.

While McKinnon’s 2016 campaign appeared catastrophic on the surface, it was not a total failure. Last year, Minnesota’s offensive line suffered a litany of major injuries and finished No. 32 in run blocking efficiency on PlayerProfiler.com. Isolating McKinnon’s efficiency apart from the offensive line, his 26.2-percent Juke Rate was No. 26 among NFL running backs and his 81.1-percent Catch Rate was No. 10.

A New Era

McKinnon needed a second chance to make a first impression, and Dalvin Cook’s torn ACL provides an opportunity for redemption.

The 2017 Vikings offense looks nothing like the 2016 Vikings offense. In 2016, behind an injury-shattered offensive line, Minnesota was near the bottom of the NFL in total run plays. Regardless of their play-calling philosophy, the Vikings were constantly playing from behind, evidenced by the negative game script. This year, the Vikings are enjoying positive game script. Based on the Vikings’ 27 run plays per game, the team is implementing a run-first philosophy, fertile ground for McKinnon to flourish.
