David Alexander -- who is training Hyde and Niners teammate Bruce Ellington (among others) in Miami -- said once Kelly was hired, the workout strategy changed to prep for a high-paced offense.
Alexander added that he wants Hyde to get down to 220 pounds or so without losing any of his power. Hyde is listed at 235. Alexander said the back is already under 230.
Hyde, 24, offers an intriguing element to Kelly's offense. The third-year pro owns the speed and agility to hit the outside zone run while maintaining power up the middle. Last month general manager Trent Baalke called Hyde the "ideal fit" for Kelly's offense.
Kelly's ground-based offense keys on picking up yards in the run game on early downs. If Hyde is gobbling up chunks of yards on first and second down, it will allow the 49ers to run the frantic pace Kelly desires.
If it all goes according to plan, Hyde will be on the field a ton in 2016. Right now, he's preparing for that possibility.
