Coach Kyle Shanahan – and his father before him – has experienced success with running backs who were not high draft picks. A year ago, some thought the 49ers might use their top pick on Leonard Fournette. But Fournette was not among the Top 3 players on the team’s draft board. The 49ers selected defensive lineman Solomon Thomas with the No. 3 overall pick after trading back one spot with the Chicago Bears. The Jacksonville Jaguars selected Fournette with the No. 4 selection. Fournette is likely to return to action Sunday against the 49ers at Levi’s Stadium after missing a game with a quadriceps injury. “It’s been proven that you can get guys (running backs) later,” Shanahan said on Wednesday. “But that by no means makes it that I’m going to say we’re never going to draft a running back high.” Fournette leads the Jaguars (10-4) with 923 yards rushing and eight touchdowns as a rookie. He has also caught 29 passes for 213 years. “When you find a special one (running back) and you think that makes sense for your team, you should never hesitate to do that,” Shanahan said.
