It didn't take long for Raheem Mostert to show off his breakaway speed this season.
In the 49ers' season-opener against the Arizona Cardinals, the running back clocked a top speed of 22.73 mph during his 76-yard reception. That made him the fastest ball-carrier over the last three seasons, according to Next Gen Stats. Mostert didn't stop there, though.
The 28-year-old running back actually had the two fastest ball-carrier speeds in the NFL during the regular season. He topped his own mark when he hit 23.09 mph on an 80-yard touchdown against the New York Jets.
Unfortunately for Mostert and the 49ers, he didn't get to show off that speed as much they'd hoped this season. Mostert played in just eight games due to knee and ankle injuries.
Over those eight games, Mostert rushed for 521 yards and two touchdowns. He averaged 65.1 yards per game and 5.0 yards per carry. If he were to keep those averages for a 16-game season, he would have rushed for slightly over 1,000 yards.
The 49ers have high hopes for Mostert. He's an explosive running back with game-changing speed. But he never has been a true lead back for a full season. He was given a chance this season but was hampered by injuries.
There's no doubt Kyle Shanahan and Co. have big plans for Mostert in 2021, if he can stay healthy.
