Hiring a new coach means the installation of a new system. Often holdover players that don’t fit that system are shipped out for players that do.

For the 49ers and new coach Kyle Shanahan, a player in that scenario might be running back Carlos Hyde, who’s entering the last year of his rookie contract when he reports for training camp on Thursday.

Hyde, 26, spent the bulk of his recent football career running zone reads out of the shotgun. That was a speciality of Chip Kelly and Hyde’s college coach Urban Meyer. Shanahan, however, runs an outside zone scheme with he running back deep behind the quarterback, who more often lines up under center.

That could make Hyde an awkward fit in the new offense. And given his contract status and the addition of four new running backs this offseason, San Francisco might be thinking of life without the 2014 second-round pick sooner than many expect given Hyde’s promising talent.

That’s what NFL Media’s Gregg Rosenthal posited this week, listing Hyde with a group of players who could be surprise cuts before the start of the regular season.

Coach Kyle Shanahan was going to be “sick” and dreaming of rookie Joe Williams if the team didn’t draft him, according to the MMQB’s Peter King. So general manager John Lynch wound up trading up to get a guy in Williams who wasn’t even on his draft board.

Compare that investment — emotional and otherwise — with the team’s lukewarm appraisals of Hyde this offseason. A talented and extremely elusive runner, Hyde has one year left on a contract signed three head coaches ago. He’s admittedly the biggest long shot to lose his job on this list, but Shanahan and Lynch are just starting their extreme makeover and have proven they are ready to act with conviction.

Shanahan and Lynch made swift changes this offseason by turning over more than half the 90-man roster, including four of six running backs, which put Hyde’s future on notice. They had no problem releasing incumbent veterans Torrey Smith and Antoine Bethea, who were deemed expendable at the start of San Francisco’s reconstruction project in March.

Williams represents a long-term solution post Hyde. Shanahan made drafting the Utah alum a priority because of his speed and one-cut running style that works within his system.

Hyde hasn’t appeared in more than 13 games since replacing Frank Gore as the starter in 2015 while dealing with a myriad of injuries. Hyde’s 988 yards rushing last season were a career high while averaging 4.6 yards per carry. He’s dealt with foot, shoulder, knee, ankle and concussion issues in his three pro seasons, and has never relented on his physical running style.

The 49ers this offseason also signed veteran Tim Hightower, traded for Denver’s Kapri Bibbs and brought in undrafted free agent Matt Breida, who has a chance at making the roster should Hyde get let go. Raheem Mostert was also brought back after having bit role last season.
