We know 49ers running back Raheem Mostert is a supreme athlete. How supreme? Well, last season, he was the third-most explosive ball-carrier in the NFL.

NFL.com's Nick Shook has been taking some deep dives into "Next Gen Stats" throughout the last few weeks, and on Wednesday, he delved into the most explosive runners the league has to offer. In order to do so, he had to establish some criteria.

In order to qualify for the top 10 most explosive runners from last season, each player had to attempt a minimum of 100 carries, at least 20 of which went for 10-or-more yards. Then, to determine the hierarchy, the percentage of runs in which they reached 15 mph or faster was the defining factor. Once the numbers were crunched, it painted Mostert in some astonishing light.

Last season, Mostert reached 15 mph or faster on an amazing 28.5 percent of his touches, which was the third-highest rate in the league behind Baltimore Ravens quarterback Lamar Jackson and Minnesota Vikings running back Dalvin Cook. To further that, he reached at least 20 mph on four rush attempts, a benchmark equaled by only seven other players; Mostert accomplished the feat with fewer total carries than any of them.

In fact, Mostert's average speed of 13.75 mph per touch ranked first among all running backs who had at least 100 touches last season. That's blazing fast. If that number is difficult to believe, well, just turn on the tape of the NFC Championship Game, in which Mostert accounted for four touchdowns and 226 yards from scrimmage on 31 total touches. I guarantee you the Green Bay Packers believe it.

Mostert seemed to pick up momentum as the season wore on, and projects to have a much bigger role in San Francisco's offense in 2020. His explosiveness is a tremendous fit for coach Kyle Shanahan's zone-blocking scheme, and there is every reason to believe the 49ers will be even more potent on that side of the ball in the season ahead.

If he stays healthy, Mostert should blow his previous career-high for touches in a season out of the water. If that's the case, well, good luck catching up to him.
